我们有一个用户模型,在用户页面上,我们希望用户留下关于其他用户的引号,因此我创建了一个user_quote模型,以及一个模式表单,用户可以在其中放置引号。
尝试创建
时出现以下错误ActiveRecord::AssociationTypeMismatch (User(#69931802297260) expected, got String(#18631480)):
app/controllers/user_quotes_controller.rb:5:in `new'
app/controllers/user_quotes_controller.rb:5:in `create'
我很确定我在协会中犯了一个错误,但经过几个小时寻找解决方案并尝试不同的事情。我以为我会问这里。
以下是相关代码:
class User < ActiveRecord::Base
has_many :quotes_made, :class_name => 'UserQuote', :foreign_key=>'quoter_id'
has_many :quotes_received, :class_name => 'UserQuote', :foreign_key=>'quotee_id'
end
class UserQuote < ActiveRecord::Base
attr_accessible :quoter_id, :quotee_id, :quote
belongs_to :quoter, :class_name => 'User', :foreign_key=>'quoter_id'
belongs_to :quotee, :class_name => 'User', :foreign_key=>'quotee_id'
end
class CreateUserQuotes < ActiveRecord::Migration
def change
create_table :user_quotes do |t|
t.integer :quoter_id
t.integer :quotee_id
t.text :quote
t.timestamps
end
end
end
class UserQuotesController < ApplicationController
def create
@uq = UserQuote.new(:params[:user_quote])
if @uq.save
render json: UserQuote.where(:quotee => @uq.quotee).to_json
else
render json: @uq.errors, status: :unprocessable_entity
end
end
end
<%= form_for UserQuote.new, remote: true, html: {'data-type' => :json} do |f| %>
<div class='modal-body'>
<%=f.hidden_field :quoter_id, :value=>@user.id %>
<div class='form-group'>
<%=f.label :quotee, {class: 'control-label'} %>
<%=f.collection_select :quotee, User.all, :id, :name, {}, {class: 'form-control'} %>
</div>
<div class='form-group'>
<%=f.label :quote, {class: 'control-label'} %>
<%=f.text_area :quote, {class: 'form-control tinymce'} %>
<%=tinymce%>
</div>
</div>
<div class='modal-footer'>
<div class='row'>
<%=f.submit "Add Quote", class: 'btn btn-default' %>
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
</div>
</div>
<% end %>
答案 0 :(得分:1)
ActiveRecord :: AssociationTypeMismatch(用户(#69931802297260)预期, 得到字符串(#18631480))
这一行
<%=f.collection_select :quotee, User.all, :id, :name, {}, {class: 'form-control'} %>
应该是
<%=f.collection_select :quotee_id, User.all, :id, :name, {}, {class: 'form-control'} %>
同样在user_quotes_controller
中,更改
render json: UserQuote.where(:quotee => @uq.quotee).to_json
到
render json: UserQuote.where(:quotee_id => @uq.quotee_id).to_json
