ADDING MORE MEMORY IN ORDER TO EXPORT (IN OE) TO EXCEL OF LARGE AMOUNT OF CHEMICALS

  1. edit filephp.ini (in Linux, /etc/php.ini)

with xxx = desired memory in megabytes

2. edit file.htaccess (in the folder install oe)

with xxx = desired memory in megabytes

SETTING FOR BARCODE SCANNER

  1. For OE original barcode, add Prefix ESC

  2. For existing barcode, (specifically for Tao Tronic scanner: https://smile.amazon.com/TaoTronics-Wireless-Cordless-Handheld-Barcode/dp/B00E0G2M6U/ref=sr_1_4?ie=UTF8&qid=1482003832&sr=8-4&keywords=taotronic+scanner ) add Prefix: [l_shift_on]+[Home]+[l_shift_off]

TO FIX ISSUE WITH IMPORT TEXT-SEPARATED TEXT FILE NOT LOADING

  • If you find a blank page after clicking the check mark :

  • Chance is you miss php-mbstring and php-gd packages

  • Install these packaged and restart apache (httpd in CentOS 7) should fix this issue

  • In CentOS 7, you can install the two above packages by running :

  • Restart your server (in Centos 7):

TO KEEP THE CURSOR ALWAYS IN THE FIRST TEXTBOX IN BARCODE TERMINAL FUNCTION

UPGRADING OE

  1. Backup current OE files

  2. Unzip the file

  3. Copy the content of the folder into your current [OE_folder] and overwrite the old files

  4. Copy the “List of files that have been modified to specific need (different than the original files of oe)” from the backed up OE to the new [OE_folder]

  5. Restart httpd and mariadb (or mysqld) services

  6. Go to web browser and access OE url

  7. Login as root into a database of interest and perform upgrade if necessary (you will have to do this again for all of the databases if major upgrade is required

MULTIPLE LABEL STYLES

This will create n number of window for different styles of label when click on this Print Dymo Label button (). Also, this code will close these pop-up windows automatically after 30 seconds (30000 miliseconds)

  1. Create the label by re-design the original file chemical_storage.label (in /oe/forms/dymo/). You can open and edit ".label" files by using Dymo software: https://www.dymo.com/en-US/online-support/dymo-user-guides

  2. Name these files as chemical_storage1.label, chemical_storage2.label, etc.

  3. Save these files in the same location: /oe/forms/dymo/

  4. Edit file edit.js (in /oe/lib/)

From:

To:

The code block above will show 2 labels in the popup window. You can add more label by copy the block for "Second label", make sure to change: - variable name for the window (window2 in the example above) - moveby specifications

CHANGING LOCATION OF MULTIPLE CONTAINERS

Note: if you want remote access then follow step 4 in this tutorial: http://www.krizna.com/centos/install-phpmyadmin-centos-7/

2. Log in into phpMyAdmin using Web browser: http://your.ip.address/phpMyAdmin/ (or https://) with root user

3. Choose the Database in which the containers belong to:

For example in this case, I choose Database storage

Screen shot 2015-07-16 at 7

4. Create new storage location in OE as usual, see:

Storages/Locations

5. Identify the storage_id of the new and old locations by choosing Table storage in Database “xyz”.

Another way of doing this is to use “Console” function in phpMyAdmin

Type in:

You should see similar to:

With the screen above, you should be able to see the storage_name and the corresponding storage_id

The next few steps is demonstration for changing all of the chemical in “315-R (Personal)” (storage_id=1) into “305-test” (storage_id=9)

In the Console:

6. To check how many chemical, type:

Note: hit Ctrl+Enter to execute command in Console

7. To change, type:

Done

CHANGING INFO OF MULTIPLE CHEMICALS

Install phpMyAdmin (See above)

To return all chemicals borrow by somebody (borrowed_by_person_id)

  1. Look up person_id by going into [Database]/person

  2. Show chemical borrow by that person (i.e. a person with person_id=8)

3. Return by:

To change the owner info of a chemical (owner_person_id)

  1. Look up person_id by going into [Database]/person

  2. Show chemical owned by that person (i.e. a person with person_id=7)

3. Change, in this case, to no owner (NULL)

Find person_id using Console command line in PHPMyAdmin

In the following example, show person_id of user with username=julia

Find storage ID using Console Command line in PHPMyAdmin

  1. First choose the desired database on the tree folder from the left

  2. Use:

Explain:

  • LIKE 'FH-2206%' : show the storage_id of the storage location with name starting with FH-2206

  • LIKE '%FH-2206%' would mean find anything with storage name containing FH-2206

  • LIKE 'FH-2206%' would mean find anything with storage name ending with FH-2206

Show chemicals with multiple criteria

Explain: the above command is used to

  • Select all of the chemical in the database that match: owner_person_id=15 AND with storage_id is NOT 18

Change Responsible person for chemicals with multiple criteria

Explain: see above for explanation of the criteria.

Show storage_name and storage_id using username

Explain:

GROUP BY storage_name : is added so that duplicates are only shown once

Update responsible person for chemicals in many location (storage)

Explain: the command above change responsible people to no one for all of the chemicals being owned by person_id=13 AND in all of the storage_id listed

Search for barcodes that are duplicated

The below command will search for all the barcode that is assigned to more than 1 container (chemical_storage). This search ignores disposed container as well as container without barcodes (chemical_storage_disabled IS NULL AND chemical_storage_barcode != "")

Update/Get extra info for containers with duplicated barcode (continued from “Search for barcodes that are duplicated”)

To select info from the list of duplicated barcodes. In this case, created by a specific user and created after some specific timestamp

REMOVE ALL CONTAINERS (BOTTLES) OF CHEMICALS

This will remove all of the containers, including info about manufactures, order date, barcode, owner, location, etc. However, info about molecule (MW, structures, safety, etc) and database related such as users will be reserved.

This is particularly helpful when you need to update a large amount of chemicals via text import.

  1. Login into your server via ssh

  2. Login into myswl using root account or user account with administrator priviledge for the database that you want to change. Replace “root” with the username if desired

3. Show database and then choose the database of interest. test is the name of the database in this example

4. Remove the chemical container by running the following command

5. (Optional): Run the command below if you want to reset the id counter (chemical_storage_id as well as autogenerated barcode)

6. Log out of mysql, restart httpd and mariadb services

7. Go back to OE website and import new tab-separated text file

Update (Oct 11, 2019): new function to delete multiple containers based on barcode has been added into Settings section. Only users with admin permission would see this option.

SETTINGS FOR OE TO USE WITH EXISTING CONTAINER BARCODES

If you have existing barcodes for your chemical containers, use the following settings

  1. Login into OE with the database that you want to modify, using an admin account, (or root account, or an account with sufficient permission)

  2. Navigate to Settings/Global Settings/Inventory

Important: when switching to this setting, you have to generate your own storage(locations) barcodes as well as user barcodes. See below for way to automatically generate location and user barcodes.

TO FIX EXISTING BARCODE IMPORTED ISSUE: Removing trailing “\n” in existing barcodes

Issue: if the existing barcode column is the last column in the tab-separated text file, when imported into OE, the “\n” will also be imported as part of the barcode. This lead to terminal window does not work with existing barcode. Use the following methods to remove this trailing “\n” character

  1. Login into your server via ssh

  2. Login into mysql using root account or user account with administrator priviledge for the database that you want to change. Replace “root” with the username if desired

3. Show database and then choose the database of interest. “test” is the name of the database in this example:

4. Remove the chemical container by running the following command

5. Log out of mysql, restart httpd and mariadb services

TO AUTOMATICALLY ADD STORAGE BARCODE WHEN USING “USE EXISTING BARCODES”

Update (as of 2019-08-01, for Khoi’s modified version): functions “Autogenerate barcode” has been added into Settings for Admin roles. Users with admin permission can login into OE web interface, go to Settings/Autogenerate barcode and click the corresponding button to autogenerate storage and/or user barcodes.

Issue: when switching to using pre-existing barcode instead of using OE-generated barcodes, the system won’t work well if no existing barcode for storages and users are added. Use the code below in mysql to automatically add barcodes for storage using OE-generated code.

While these barcodes look the same, they have to be generated in order for terminal to work

  1. Login into your server via ssh

  2. Login into mysql using root account or user account with administrator privilege for the database that you want to change. Replace “root” with the username if desired

3. Show database and then choose the database of interest. “test” is the name of the database in this example:

4. You can check if the new generated barcode first by running this in phpMyAdmin (easier to see result). See explanation below for the complicated function. Compared the “new_barcode” with the autogenerated barcode to make sure the function work well.

5. Update the “storage” table, by setting “storage_barcode” field. “storage_barcode” field is a binary so cast() was used. Note, this whole function inside cast() is to convert “storage_id” field to EAN8 barcode. See here for more info on how to make EAN8 barcode: http://www.barcodeisland.com/ean8.phtml

Explain: default in OE, the barcode for storage is “92xxxxxy” with the last digit “y” (digit number 8 on 1-based) is the check sum of the first 7 digits. The “xxxxx” labeled in red is the “storage_id” left padded with “0” (number zero).

For example: if “storage_id”=1 => “storage_barcode”=92000018

  1. Exit mysql:

TO AUTOMATICALLY ADD PERSON BARCODE WHEN USING “USE EXISTING BARCODES”

Update (as of 2019-08-01, for Khoi’s modified version): functions “Autogenerate barcode” has been added into Settings for Admin roles. Users with admin permission can login into OE web interface, go to Settings/Autogenerate barcode and click the corresponding button to autogenerate storage and/or user barcodes.

Issue: when switching to using pre-existing barcode instead of using OE-generated barcodes, the system won’t work well if no existing barcode for storages and users are added. Use the code below in mysql to automatically add barcodes for USER using OE-generated barcode.

While these barcodes look the same, they have to be generated in order for terminal to work

  1. Login into your server via ssh

  2. Login into mysql using root account or user account with administrator privilege for the database that you want to change. Replace “root” with the username if desired

3. Show database and then choose the database of interest. “test” is the name of the database in this example:

Explain: default in OE, the barcode for PERSON is “91xxxxxy” with the last digit “y” (digit number 8 on 1-based) is the check sum of the first 7 digits. The “xxxxx” labeled in red is the “person_id” left padded with “0” (number zero).

For example: if “person_id”=1 => “person_barcode”=91000019

6. Exit mysql:

SETTING TO ALLOW SEEING LOCATION OF CHEMICAL OUTSIDE YOUR OWN GROUP

In the default setting of OE, the exact location of a chemical belonging to a different group is masked. This setting will help you to allow some specific person or everyone to be able to see locations of chemicals outside of your own groups

  1. Login into the server via ssh and then convert to root user or use sudo command. The following is using sudo command

  2. It is a good idea to save an original copy of this file first. Modify the file lib_output.php inside open enventory folder. In this example, the open enventory folder is named “oe”. The specific location of your folder might change. Change the path accordingly.

3. Change the content of the file as follow. Note, this is on line 2584 so google to search for some term in vi; otherwise you will need to scroll a lot.

Original content:

To let EVERYONE see the locations:

To let a specific user to see the location, change the content as follow. In this example, the person name is “special_person

UPLOADING EXISTING LOCATION BARCODES

Below guide is referenced from:

Prepare the excel file with one column as storage with the same name as those found in OE. Export to csv file, csv file does not have to have the same column but it is best to have the first 2 columns is the storage name and barcode

Use mysql command line. ( if you use phpMyAdmin console, see section below)

  1. Login into mysql as root user using:

2. Show all databases and choose the correct database to modify (in this example “test” is the name of the database):

3. Create a temporary table (in this example temp_storage is the name of the database, storage and barcode are the 2 headlines of the 2 columns):

4. Load csv data file into temp_storage table (in this example test is the name of the database; “ignore 1 lines” because the csv file head 1 line headline):

5. Update storage table

6. Remove the temporary table

If you want to use phpMyAdmin,

  1. Copy csv files into /var/lib/mysql

  2. Open phpMyAdmin console.

  3. Choose the right databases

4. Run ALL of these commands AT ONCE (Ctrl-Enter to run command(s) in phpMyAdmin console)
