I'm trying to use rails_admin for the first time and I'm getting the following error during installation:
'table_structor': Could not find table 'views'
I've never had a model named 'views', so I'm not even sure why it's looking for this. Any ideas what may be causing this?
Check your models folder. You probably have a rouge model you aren't using.

I've a problem with Neo4jrb 8.1.1, Rails 5.1.1, Neo4j 3.2.0 CE
I have a City model with an Int id, the DB is read only with data imported from csv files.
What should I declare to get rid of the error?
So far, I thought that declaring
id_property :id
property :name
would be fine but it doesn't work.
Overall, I'm annoyed with these new migrations files because the Neo4J DB is already done, I'm not supposed to write or modify indexes or constraints.
What's the error message you're seeing? I imagine you can solve the issue by creating an initializer and manually adding the relevant constraint(s) to the ModelSchema. Something like Neo4j::ModelSchema.add_defined_constraint(City, :id). It's also possible that this could be done inside the Model itself. Some experimentation should solve the problem.
See the source code for more info:

I have been chasing an issue down for a while now, and still cannot figure out what's happening. I am unable to edit documents made from my gem through normal persistence methods, like update or even just editing attributes and calling save.
For example, calling:
Scram::Policy.where(id: a.id).first.update!(priority: 12345)
Will not work at all (there are no errors, but the document has not updated). But the following will work fine:
Scram::Policy.collection.find( { "_id" => a.id } ).update_one( { "$set" => {"priority" => 12345}})
I am not sure what I'm doing wrong. Calling update and save on any other model works fine. The document in question is from my gem: https://github.com/skreem/scram/blob/master/lib/scram/app/models/policy.rb
I cannot edit its embedded documents either (targets). I have tried removing the store_in macro, and specifying exactly what class to use using inverse_of and class_name in a fake app to reimplement these classes: https://github.com/skreem/scram-implementation/blob/master/lib/scram/lib/scram/app/models/policy.rb
I've tried reimplementing the entire gem into a clean fake rails application: https://github.com/skreem/scram-implementation
Running these in rails console demonstrates how updating does not work:

Is this an issue with mongoid concerning embedded documents, or is there some small intricacy I am missing in my code?
EDIT:
The issue continues if you run irb from the root of my gem (scram) and then run the following:
require "scram.rb"
Mongoid.load!('./spec/config/mongoid.yml', :test)
Scram::Policy.first.update!(priority: 32) #=> doesn't update the document at all
Scram::Policy.where(id: "58af256f366a3536f0d54a61").update(priority: 322) #=> works just fine
Oddly enough, the following doesn't work:
Scram::Policy.where(id: "58af256f366a3536f0d54a61").first.update(priority: 322)
It seems like first isn't retrieving what I want. Doing an equality comparison shows that the first document is equal to the first returned by the where query.
Well. As it turns out, you cannot call a field collection_name or else mongoid will ensure bad things happen to you. Just renaming the field solved all my issues. Here's the code within mongoid that was responsible for the collision: https://github.com/mongodb/mongoid/blob/master/lib/mongoid/persistence_context.rb#L82
Here's the commit within my gem that fixed my issue: https://github.com/skreem/scram/commit/25995e955c235b24ac86d389dca59996fc60d822
Edit:
Make sure to update your Mongoid version if you have dealt with this issue and did not get any warnings! After creating an issue on the mongoid issue tracker, PersistenceContext was added to a list of prohibited methods. Now, attempting to use collection_name or collection as a field will cause mongoid to spit out a couple of warnings.

I am adding thousands of entries to my database through seeds.rb and a CSV file. In order to do so I am using Fast_Seeder:
FastSeeder.seed_csv!(Artist, "artist_sample.csv", :name, :sort_name)
I use Friendly-id, and as it is now, it is not creating a slug because I am not feeding it through the file.
How do I go about creating it without having to change the file manually?
Any help would be much appreciated!
I'm not familiar with Fast_Seeder, but I am with friendly-id. Their docs say the following:
# If you're adding FriendlyId to an existing app and need
# to generate slugs for existing users, do this from the
# console, runner, or add a Rake task:
User.find_each(&:save)
It would obviously be more efficient to get friendly-id playing nice in the first place, but barring that you can add that the next line. You basically just need to tap validation. I bet .find_each(&:valid?) might work too. This leads me to wonder if FastSeeder is creating these records without hitting your validations.
EDIT: Yup, I just dug through their source and they are creating straight through the database. You'll probably need to go the route I outlined above.
I was trying to make work this:
http://chainselects.hypermediasoft.com/
But got error:
Routing Error
uninitialized constant ChainSelectsHelper
So i have to make some break and ask community - is there any easy way to make chaining select boxes for my application forms?
UPDATE:
Maybe i should make editions in some config files? I can see thist ChainSelectsHelper in vendor/plugins/ChainSelects/lib/app/helpers/chain_selects_helper.rb. But why my application can't see this? Any assets pipeline configs needed?
And got this error in model:
undefined method `acts_as_chainable' for #<Class:0x007fe387542780>
From the looks of it, it seems that you did not add this in the controller:
include ChainSelectsHelper
Keep in mind that modifications have to be made to both model and controller, as stated here.
I'm in the midst of converting an old Rails2.3 project to 3, and I'm running into this runtime error when I load the first page:
Missing helper file helpers/activesupport.rb
Full stacktrace here
Has anyone else run into this? Looks like something changed in how helpers are loaded, but I don't see any obvious solutions.
I was able to work around the problem by created an empty file at app/helpers/activesupport.rb but I would like to know why this is happening in the first place.
Could it be a clash with ActiveSupport?
I am not sure why its even looking for such a helper - do you have a model or controller called activesupport?
I was having a similar issue with Hpricot. I had a require 'hpricot' statement in a helper, but I didn't have Hpricot in my Gemfile.
In your case, if you were explicitly requiring ActiveSupport somewhere, you would have to add it to your Gemfile (I just tried it and despite having Rails in my Gemfile, I still got the same error you were getting).
