wish of those help A whole bunch of things and hard to help without actually running the code.
First of all, familiarize yourself with good practice in regards of naming things. @catalogs.each do |pc| is a no-no and should be @catalogs.each do |catalog|.

wish help you to fix your issue That's perfectly sensible.
The only risk (and it's a miniscule one) is that you are possibly subject to a race condition. For example, someone could change the post's category after you fetched the categories list, or they could update the list of categories, and what you're showing would no longer be correct. Subsequently, if they, say, clicked on a category name to get a list of all posts with that category, they'd probably get an error unless you were handling that sort of thing.

this one helps. A wild guess: ruby snippets are loaded for .rb extensions but rails snippets are not.
Do you use this version of SnipMate? If so there seems to be a possibility to use extra snippets for a given filetype.

Hope that helps In development mode, your class is going to get reloaded with every request, so the value that's set in an initializer at app startup will not persist when the class is reloaded after the first request. (The result of "config.cache_classes = false" in your development.rb).
However, if you want to set a value in an initializer and have it persist in development mode, you can either add it as a constant:
code :
 SALT='savory_hash'
 module YourAppsName
  class Application < Rails::Application
   config.token_salt = "savory_hash"
  end
 end
 Rails.application.config.token_salt

Ruby on Rails: email_field has value inserted when page loads

Ruby on Rails: email_field has value inserted when page loads

it helps some times you should have a form_for @user (or similar) line above. The local variable is filled by your controller. Look at the controller code, if there is something that fills in the "'" or look at the model if there is a default, that sets the email field to "'".
To change the schema definition of the user data create a new db mirgration:
code :
rails generate migration no_default_for_user_email
def up
    change_column :users, 'email', :string, default: ""
end

def down
    change_column :users, 'email', :string, default: "'"
end
