I am trying to migrate my app to heroku and this error came up, causing a rollback of my migration. Can anyone tell me why is there an error with date_time?

It should be datetime not date_time. Read the documentation.
Change this line
add_column(:articles, :created_at, :date_time)
in your migration to
add_column(:articles, :created_at, :datetime)

def change

end
end
In your migration file you have defined user_id as an integrer instead of an integer
You've just need to update your migration file with a valid type
Check this line of your logs :
PG::UndefinedObject: ERROR: type "integrer" does not exist
LINE 1: ALTER TABLE "pins" ADD "user_id" integrer
It clearly states that you have mistyped "integer" with "integrer". Please correct that in your file.

I tried deleting my old heroku app and starting a new one to reset the migrations (worked to "troubleshoot" in the past) but it didnt work this time. All of the migrations are showing up when I ran heroku rake db:migrate except the remember digest one. I ran db:migrate again but can't get it to migrate. Here are migrations:

Is there a reason that this migration may not be going through? Running db:migrate again doesn't give any results. Any information on where you think the problem may be located even would be helpful, I cannot find any info on what's causing this.
My problem was that git wasn't tracking any of the sessions files I had added, so they were on my local computer but not on github->heroku. I found this out by making a change only on sessions_helper, then committing to git only to get a message that there were no changes to any files but several (all of the sessions files) were untracked.
Happened because I used git -am "commit message" rather than git add -A first bc I thought the -a flag added everything. Should've checked git to make sure sessions_helper.rb was there, all the answers told me to check this but I was only checking on my local machine.

I'm using sqlite for this particular project. I've read a few things about heroku using Postgres and case sensitivity. Unfortunately, this doesn't help my issue because I created the column label in lowercase anyways.
I'm a heavy noob and this is the first Heroku error that I have encountered. I can't even tell where the logs are tracing the error back to. Any light that you can shed is much appreciated. Please let me know if there are any other files that I need to provide.
You might have run the migration locally but have you run it on Heroku?
heroku run rake db:migrate
will do that for you
Things to check:
First, make sure the column exists in your local database (SQLite):
$ rails db
sqlite> .schema users
Next, make sure the column exists on Heroku (PostgreSQL):
$ heroku pg:psql
psql> \d+ users
Possible problem:
After you added the remember_token to your User model, you may have forgotten to commit your code to your Git repository before pushing to Heroku. Run:
$ git status
This will show you if you have any modified files that you haven't committed yet.
