How to achieve simple scoping in your views such as:
<% if @user.admin %>
where "admin" is the following scope in user.rb:
scope :admin, where(role: "admin")
there is a column Role which is a string in the Users table
I've done the same thing before with another Model (but not a devise user model) to which I could later call
<% if objective.completed %>
right after calling an each method in the objectives.
However When I do the exact same thing to a user model I get an
undefined method `admin' for #<User:0x00000107e39038>
How could I make it work? I've been digging for hours.
For a no scope workaround try:
<% if @user.role == "admin" %>
You simply can't use scopes this way. Scopes are used as class methods, so if you run
User.admin
it returns list of users matching given condition. What you need is an instance method. Add it to your user.rb file:
def admin?
admin == 'admin'
end
and you will be able to use it in your view:
- if @user.admin?
anyways, you should definitely reconsider storing roles as string in users table. Try to create another table called roles.
