Having trouble with boolean method in Rails?

+1 vote
374 views

I'm checking if a user is an admin, and then I will show a delete button if he is. For whatever reason, it's automatically setting the boolean to true. It says is_admin: false in the console when I pull up the user's record.

Check status of user
def is_admin?
 self.username
end

view method

Have any ideas to why the method is still showing the button?

 Check status of user
 def is_admin?
 self.username
 end

This method is going to return the username, which is probably set to something, and that means true when you ask this way. You probably meant to check if the admin attribute on that user model.

What is the best method to manage image uploads in Rails

What is the best method to manage image uploads in Rails? Is there a tool that allows auto-resizing upon image upload based on predefined dimensions? Moreover, is there any tool available that makes it possible to render / regenerate the same originally uploaded image using alternative view based styles, e.g. thumbs, 320x200 or 640x480 etc..?

Is find() a class method or instance method in Ruby on Rails?

In the following code - 

 require 'active_record'

 class Order < ActiveRecord::Base
 end

 order = Order.find(1)
 ...

As per http://api.rubyonrails.org/ find() is an instance public method. So why can we call Order.find(1) here? Shouldn't it be Order.new.find(1)?

using mongodb with ActiveRecord or other in Ruby on Rails

We recently looked at mongoDB a bit. I was discussing using mongoDB with active record but was told that maybe there are other or better options. Can someone comment on that ?

Also, someone suggested storing a ruby array directly inside of a record where I would have opted for the array to be a separate set of records in active record using has_many and belongs_to .. It seemed to me that how I search on those child records would be a big factor but I soon realized I need to find out what are the options. Do people store arrays and hashes directly in mongo DB fields or is that not the best way to go ?

Session variable in default_scope with rails App

I have a project model which I'd like to set the default_scope to filter out projects where the user doesn't have permission to view them.

Think something along the lines of the projects having a list of teams and companies that the user must be in to access the data.

default_scope seems to work well if I hard code it as I really don't want a dev to accidentally not have these permissions filters in use. The lists of teams and companies a user is in is stored in the session.
