How to limit the Drupal 8 & 9 Content view to show only editable content

Thankfully, there is a module for that, but the documentation isn’t great.

  1. Install the Views Node Access Filter module
  2. Edit the Content view (URL:, UI Path: Structure > Views > Content > Edit)
    Views Node Access Filter module view edit
  3. With Default display selected, click add a Filter Criteria
    Views Node Access Filter module add filter
  4. Check Editable and click Add and configure filter criteria
    Views Node Access Filter Module Editable
  5. Click Apply
    Views Node Access Filter Module Apply
  6. Save the view
    Views Node Access Filter Module Save

Now the Content view will only show the user the content that they are able to edit.

Drupal 8 & 9 check if current page is user

You may want to check programmatically if you are on a user page or profile in Drupal 8 or 9. Use Drupal’s routeMatch to grab user. Then check if $user is an instance of user. Execute your code on that page.

$user = \Drupal::routeMatch()->getParameter('user');
if ($user instanceof \Drupal\user\UserInterface) {
  // It's a user page!

Mac OS Terminal Custom Prompt with Git Branch

This article explains how I set up my new Mac’s terminal to be more simple and incorporate the Git branch in the prompt.


Get the code from the source on GitHub.

As directed in the comments, place the code in your home directory (e.g. ~/ You will most likely need to create this file.

Add or edit .bashrc or .zshrc

You will need to know what shell you are running. A really easy way to see this is to just type some gibberish in the terminal prompt and hit enter.

bash: asdf: command not found

The above shows you are running the Bash shell. Below shows you are using the ZSH shell.

zsh: command not found: asdf

Create or edit your .bashrc or .zshrc file in your home directory (e.g. ~/.zshrc). Then add the following to your file and save:

Bash Shell

source ~/
PS1='[\u@\h \W$(__git_ps1 " ({5eae014a9d3ebefef46f176d33543e78fecc824a150a3220e1441ced9189d4b1}s)")]\$ '

ZSH Shell

source ~/
setopt PROMPT_SUBST ; PS1='[{5eae014a9d3ebefef46f176d33543e78fecc824a150a3220e1441ced9189d4b1}n@{5eae014a9d3ebefef46f176d33543e78fecc824a150a3220e1441ced9189d4b1}m {5eae014a9d3ebefef46f176d33543e78fecc824a150a3220e1441ced9189d4b1}c$(__git_ps1 " ({5eae014a9d3ebefef46f176d33543e78fecc824a150a3220e1441ced9189d4b1}s)")]\$ '

Reload Shell rc File

Run the following command to reload your RC file.

Bash Shell

source ~/.bashrc

ZSH Shell

source ~/.zshrc

Your New Prompt

Your new prompt will look something like this depending on if you are in a git repository or not:


There are many options to customize your prompt even more by customizing what you put in your RC file. Doing a search on google will help you find what you need.

Migration From Drupal 7 to Drupal 8: How do I find which items were ignored?

You are migrating from Drupal 7 to Drupal 8 and you have ignored items after you run a migration. This leads to the very important question of which ones were ignored?

What you see

[notice] Processed 632 items (630 created, 0 updated, 0 failed, 2 ignored) - done with 'node_form'

The above is what I will use in my examples.

What you want to know

What are the items ignored!? For this we can look into the database. I assume you have access to a console…

The migrate_map_migration_name table in your database will give you the information you need. There will be a column named source_row_status. The value of 2 equals the status of ignored. So run the following MySQL command:

SELECT * FROM `migrate_map_node_form` WHERE source_row_status = 2;

The sourceid1 column of the returned rows will contain the id of the item that was ignored.

Example output:

source_ids_hash sourceid1 destid1 source_row_status source_row_status last_imported hash
8530eb5d63ad4cfea47134a28e3339e089f639164d218287c3… 10931 NULL 2 0 0
ddd550e747c2a26a2a5058d49be0e146616fd5c45f6bef88f3… 11656 NULL 2 0 0

Migration of Files from Dupal 7 to Drupal 8 with: [notice] Field discovery failed for Drupal core version 7. Did this site have the CCK or Field module installed? Error: No database connection configured for source plugin d7_field_instance

When migrating files in Drupal 7 to Drupal 8 you receive one or more notices:

[notice] Field discovery failed for Drupal core version 7. Did this site have the CCK or Field module installed? Error: No database connection configured for source plugin d7_field_instance

At the end of the migration you will see something like this:

[notice] Processed 2607 items (2474 created, 0 updated, 15 failed, 118 ignored) - done with 'file'

The numbers will be different according to the amount of files you are migrating. In my case each of the 118 ignored files all had generated [notice] Field discovery failed....

After looking through the database I found that one of my fields held reference data to a user that no longer existed.

Process I took to find the problem

  1. Google and Drupal site
    1. There was very little information to be found with searching for: [notice] Field discovery failed for Drupal core version 7. Did this site have the CCK or Field module installed? Error: No database connection configured for source plugin d7_field_instance.
  2. Dive into the database – splash
    1. Find which files didn’t get migrated from the migration map with MYSQL on the D8 database.
      SELECT * FROM `migrate_map_file` where source_row_status <> 0;
      You’ll want to note that all the files that don’t have a d8_database > migrate_map_file > migrate_map_status of 0 are not created. The status of 2 means the file is ignored and 3 means it failed the migration.
    2. Use MYSQL on the D7 database to select a few files each that were ignored and created.
      SELECT * FROM `file_managed` WHERE fid = 5981 OR fid = 6051 OR fid = 5816 OR fid = 6906 OR fid = 16231 OR fid = 3709
      The file_managed table is where you can pull each FID (field id) from the fid column. In the example the last two FIDs where files that were created. The other 3 FIDs where ones that had been ignored. By comparing these I found that the only thing that stood out was the UIDs (user ids). A couple of the files ignored had the same UID.
    3. On the Drupal 7 site I viewed the user by the UID ( This ended up in a page not found. You can also check this in the database with the following command.
      SELECT * FROM `users` WHERE uid = 123;


There were files with an author that no longer existed in the database. As an example, the file with the FID of 5981. This file referenced the author, which was a user, with a UID of 123 that was no longer in the database. This caused the notice and for the file to be ignored in the migration.

How to pay Minnesota sales tax and record it in QuickBooks Desktop

  1. Set up sales tax in QuickBooks Desktop
  2. Make sales and collect sales tax
  3. Run report Reports > Vendors & Payables > Sales Tax Liability
    1. This will give you the numbers for your sales tax liability
  4. Log into MN e-Services
    1. File the appropriate quarter
    2. Enter the information from your sales tax liability report
    3. Pay sales and use tax
    4. Print transaction for your tax records
  5. In QuickBooks navigate to Vendors > Sales Tax > Pay Sales Tax
    1. If you have paid your previous sales tax appropriately you should only have the last quarter’s tax numbers listed
    2. Confirm the check date is the date you paid the taxes
    3. Confirm you have the last quarter date selected
    4. Adjust the tax amount as needed Note: Minnesota rounds the amount to whole dollars. This will mean that you will have to adjust the tax paid up or down.
      1. Click Adjust
      2. Confirm that the Adjustment Date is the date you paid the taxes
      3. Select your Sales Tax Vendor
      4. Select your Adjustment Account
        Note: If you round down you will recieve a credit. That credit needs to go somewhere in QuickBooks so you will have to set up an Income account to track it. The same is true if you have to round up. Except for this you will need an Expense account. Reference
      5. Select the type of adjustment. Increase Sales Tax By for rounding up (or if you have to pay a late fee) or Reduce Sales Tax By for rounding down.
      6. Enter the Amount of the increase or reduction
      7. In the memo I find it helpful to enter the reason for the adjustment (e.g. Sales Tax Adjustment – Round up)
      8. Click OK
    5. Select each of the line items you would like to pay including any adjustments
    6. Click OK
  6. That is it you have paid for your taxes and tracked them in QuickBooks

Just a note… I am not an authority figure on QuickBooks. This is just what has worked for me.


I had a mess when I paid the taxes in QuickBooks with a check instead of the Pay Taxes feature. I had to make some adjustments. See the Sales Tax Payable is incorrect after using the Write Cheques window to pay sales tax heading on the How to resolve common sales tax issues QuickBooks page.
