strong-parameters

问题 One StackOverflow question has asked what I need, but the self-answer didn't help me know what to do next. The scenario presented in that question (whitelisting deeply nested strong parameters in rails) is pretty much what I've got going on, but I'll post an abbreviation of mine (still very long) and hope someone--maybe even the Dave of the post--can help (I don't have enough reputation to comment and ask him). There are few links about nested strong parameters I haven't read, and I've dealt

问题 I want to create records on two different tables (venue and parking) via one form using accepts_nested_attributes_for. I want a user to be able to create a new venue, and also specify the parking options available to that venue via checkboxes. When I submit the form, the record for the containing model (venue) is created, but nothing happens with the nested model (parking). When I check the response from the server, I see that I'm encountering "Unpermitted parameters: parking_attributes,"

问题 I'm using Rails 4 with Devise, Cancan and Rollify. I've got an index of users with a modal to change the role.

问题 I'm using Ember with ember-data and a rails api. I had a createRecord() and save() for the record that was working fine. The payload in the network tab for the post request to create the record in rails looks like: {data: {attributes: { foo: 'bar' } } . In the rails controller, I have strong params like so: params.require(:data).require(:attributes).permit(:foo) , which was working fine for a little while. Now when I send the request rails says that param is missing or the value is empty:

问题 I have this in my controller: params.require(:item).permit! Let's assume this rspec spec: put :update, id: @item.id, item: { name: "new name" } It works as expected, no error. However, if I use this: put :update, id: @item.id, item: nil I get ActionController::ParameterMissing which I don't want to get. It has to do with controller macros that I use for other actions and through which I cannot control the params being sent (the macros checks for user credentials, so I don't really care about
