问题 I saw the railscast on using deeply nested forms to make a survey: http://railscasts.com/episodes/196-nested-model-form-revised?view=asciicast How would you construct something similar in Rails to actually /take/ the survey, instead of just construct it for display in text? How would you make a deeply nested form containing a survey form the user fills out? 回答1: Couple things to consider: Use fields_for (this is to construct child form). Use nested_form to keep building child forms (n amount)

问题 I am trying to make an app with Rails 4. I use simple form gem for forms and am trying to use Cocoon gem for nested elements of the forms. I asked this question, which explains what I'm trying to achieve in more detail: Rails - Multiple entries for a single attribute I have a profile model and a qualifications model.

问题 I am at the moment creating a complicated rails form for 1:n relationship with nested form and collection select with values from yet another data table. So far, it overwrites the database value with the first entry in the values list of the collection_select whenever the user does not select the correct value before update. I still need to set the initial value in the collection_select correctly. I have read a lot of questions on SO already, most relevant was: f-collection-select-not

问题 i am following Ryan Bates episode on nested form fields and have added the bit of jquery suggested at the end of part 2. Everything works well(i am able to add fields and remove fields). i now want to limit the number of fields you can add in the form. in my application.js i have function add_fields(link, association, content) { var new_id = new Date().getTime(); var regexp = new RegExp("new_" + association, "g") $(link).parent().before(content.replace(regexp, new_id)); } as Ryan Bates has

问题 I'm running: rails 4.1.4 devise 3.3 I used the RailsApp starter app to set up devise and pundit. Right now I am having trouble making a nested form attribute save. I am getting an error: Unpermitted parameters: players I edited the initializer file to show: def configure_permitted_parameters devise_parameter_sanitizer.for(:sign_up) { |u| u.permit(:first_name, :last_name, :players, :player_attributes => [:position]) } devise_parameter_sanitizer.for(:account_update) { |u| u.permit(:first_name,

问题 I am having an issue with creating nested resources in my admin namespace. I am somewhat new to namespaces. I have read several posts on Stack but to no avail, perhaps i am implementing this incorrectly. I have an admin model (devise), and am trying to nest an address to the custom user show page I have created, this is where the problem is. When trying to create a new address for an admin I get this error when I submit the form: ActionController::UrlGenerationError at /admin/admins/2CE0

问题 I've followed Cocoon's instructions for creating a nested form for a has_many association but there's one thing that I can't seem to figure out. I'm able to add an existing genre to my project but when it comes to creating a completely new one the parameters for my genres aren't being permitted. When I refer to my rails console to debug the issue this is the message I receive upon update: Unpermitted parameters: genre_attributes What's strange is I've permitted both my join table genreships
