RSpec - Testing Strong Parameters ActionController::ParameterMissing

由 喜欢而已 提交于 2019-12-08 03:15:13
问题 How can one test if a certain action raises an ActionController::ParameterMissing exception? For example: it "raises an exception" do post :create, {} expect(response).to raise ActionController::ParameterMissing end The above does not seem to work, it will fail the test with the ActionController::ParameterMissing exception. 回答1: Use the expect block syntax using the raise_error matcher: it "raises an exception" do expect{ post(:create, {}) }.to raise_error ActionController::ParameterMissing

How to use Rails Action Controller Nested Params to Permit a Specific Attributes Hash

由 十年热恋 提交于 2019-12-07 09:03:23

I expected this to work: params.require(:book).permit(:title, :description, style: {:font, :color}) But it resulted in a syntax error. This, however, worked: params.require(:book).permit(:title, :description, style: [:font, :color]) But my issue with this, it it seems to permit style values that are arrays of

由 社会主义新天地 提交于 2019-12-07 08:27:08
问题 I have two associated models in my Rails 4 app: product.rb and image.rb . The Image model allows attached files using the Paperclip gem. Images belong_to a Product, and a product has_many Images.

whitelisting deeply nested strong parameters in rails

由 ≯℡__Kan透↙ 提交于 2019-12-06 15:23:12
问题 I'm trying to store a serialized Ransack search in a text column. It's deeply nested and I'm struggling coming up with permit call for it. Here's a sample hash: { "c"=>{ "0"=>{ "a"=>{ "0"=>{ "name"=>"column_1" } }, "p"=>"eq", "v"=>{ "0"=>{ "value"=>"value_1" } } }, "1"=>{ "a"=>{ "0"=>{ "name"=>"column_2" } }, "p"=>"cont", "v"=>{ "0"=>{ "value"=>"value_2" } } } } } How would you write a permit for that? This is my best guess for reading the doc but it isn't working. def course_listing_params

It works without the permit keyword. My create method looks like this: def create @post = Post.new(post_params) @post.save redirect_to @post end I'm working with Rails 4.0 and Ruby 2.0. Any idea why the strong parameters security function isn't working? 回答1: The documentation is
