Using curl to test Rails routes
I have a model called users that I want to update using an API. The way I thought to do this is by creating an update route and plugging in code that does the updating. I created a test using RSpec and it seemed to work, however, I want to actually see the changed data in my database so I was trying to use curl to update my development database.
I tried the command
curl -X PUT -d "attribute1 = value1, attribute2 = value2" http://localhost:3000/users/1
but I got an error
<html xmlns="http://www.w3.org/1999/xhtml">
<head>

NoMethodError

<pre>You have a nil object when you didn't expect it! You might have expected an instance of ActiveRecord::Base. The error occurred while evaluating nil.[]</pre>

Heres's the relevant line in the routes.rb
resources :users, :only => [:create, :update, :destroy]
Here's the relevant code in the controller
def update
@user = User.find(params[:id])
if params[:user][:attribute1] == ("x" || "y" || "z")
params[:user][:attribute3] = Time.now
end
@user.update_attributes(:user)
render :nothing => true
end
And finally here's the spec code that passed
describe "PUT 'update'" do
before(:each) do
@user = Factory(:user)
end
describe "success" do
it "should be successful" do
put :update, :id => @user, :user => { :attribute1 => "x", :attribute2 => "xyz"}
response.should be_success
end
it "should update attribute" do
old_attribute = @user.attribute3
put :update, :id => @user, :user => { :attribute1 => "x", :attribute2 => "xyz"}
@user.attribute3 != old_attribute
end
end
end
I tried to find a good curl tutorial to check my syntax but i could only find examples, so I'm not too sure if the syntax is right.
your PUT data should look like this:
user[attribute1]=value1&user[attribute2]=value2
Similar to the way you'd construct parameters on the query string of a URL.
When calling curl, you would have to send your attributes like this: user[name]=John&... Did you do that?
