Rails devise: create association on user sign_up

Question

As a total Ruby noob i need to do a simple thing but doing it the ruby way is not clear for me.

What is want to do is the following:

I have a devise User model with a one to one association "Account"

In the devise registration view i want to add extra form fields for this account, and that is where i am stuck.

It seems i cannot add the account fields to the view

for example this will not work:

# address is a field of Account
<%= f.text_field :address %>

How can i bring the Account model into the scope? Or is there a way to do something like this

<%= f.text_field :account['address'] %>

I have really no clue how to add account into scope or how i can access the User assoc Account properly.

Thx for the help

Answer 1

You need to use accepts_nested_attributes_for :account to able to add parameters from registration form. Then whitelist these parameters by overriding devise method configure_permitted_parameters.

def configure_permitted_parameters
    devise_parameter_sanitizer.permit(:sign_up, keys: [account_attributes: [:address]])
end

You might need to change which parameters needs to be whitelisted.

Then in view, you need to use fields_for like

f.fields_for(:addresss) do |address_fields|
  <%= address_fields.text_field :address %>
end

Hopefully, this solves the problem. Try to search about nested attributes if something doesn't work.

您需要从那里重写devise RegistrationsController ，然后在用户成功注册后在create方法上进行修改以建立account记录
