我收到了一堆失败的测试(准确的21)/网站上的错误消息。ActiveRecord :: StatementInvalid在用户#show Rails教程第12章
这里是在网站上的消息:在用户#
的ActiveRecord :: StatementInvalid显示
显示rails_projects/sample_app /应用/视图/共享/ _stats.html.erb其中线#11提出: SQLite3 :: SQLException:在“id”附近:语法错误:SELECT COUNT(*)FROM“users”INNER JOIN“relationships”ON“users”.id =“relationships”.follower_id WHERE((“relationships”。 followed_id = 101))
它也拉起“提取s乌尔斯河(大约线#11):”
8: </span> </a>
9: </td> <td>
10: <a href="<%= followers_user_path(@user) %>"> <span id="followers" class="stat">
11: <%= pluralize(@user.followers.count, "follower") %> </span>
12: </a> </td>
13: </tr>
14: </table>
Trace of template inclusion: app/views/users/show.html.erb
另外:
app/views/shared/_stats.html.erb:11:in `_app_views_shared__stats_html_erb__1272198506242050260_70324836955760_711623751783882131'

当我带走
<%= pluralize(@user.followers.count, "follower") %>
线路,站点工作(和我的测试失败降至6 )。
失败的测试似乎有一个类似的SQL错误。下面是失败的测试:
rspec ./spec/controllers/users_controller_spec.rb:313 # UsersController DELETE 'destroy' as an admin user should destroy the user
rspec ./spec/controllers/users_controller_spec.rb:319 # UsersController DELETE 'destroy' as an admin user should redirect to the users page
rspec ./spec/controllers/users_controller_spec.rb:355 # UsersController follow pages when signed in should show user followers
rspec ./spec/models/user_spec.rb:185 # User micropost associations should destroy associated microposts
rspec ./spec/models/user_spec.rb:265 # User relationships should include the follower in the followers array
这里是错误(分别),他们得到:
1. Failure/Error: delete :destroy, :id => @user
ActiveRecord::StatementInvalid:
SQLite3::SQLException: near "id": syntax error: SELECT "relationships".* FROM "relationships" WHERE ("relationships".followed_ id = 1)
2. Failure/Error: delete :destroy, :id => @user
ActiveRecord::StatementInvalid:
SQLite3::SQLException: near "id": syntax error: SELECT "relationships".* FROM "relationships" WHERE ("relationships".followed_ id = 1)
3. Failure/Error: get :followers, :id => @other_user
ActiveRecord::StatementInvalid:
SQLite3::SQLException: near "id": syntax error: SELECT "users".* FROM "users" INNER JOIN "relationships" ON "users".id = "relationships".follower_id WHERE (("relationships".followed_ id = 2)) LIMIT 30 OFFSET 0
4. Failure/Error: @user.destroy
ActiveRecord::StatementInvalid:
SQLite3::SQLException: near "id": syntax error: SELECT "relationships".* FROM "relationships" WHERE ("relationships".followed_ id = 1)
5. Failure/Error: @followed.followers.should include(@user)
ActiveRecord::StatementInvalid:
SQLite3::SQLException: near "id": syntax error: SELECT "users".* FROM "users" INNER JOIN "relationships" ON "users".id = "relationships".follower_id WHERE (("relationships".followed_ id = 2))
这里是我的 “_stats.html.erb” 文件:
<% @user ||= current_user %> <div class="stats">
<table summary="User stats">
<tr>
<td>
<a href="<%= following_user_path(@user) %>">
<span id="following" class="stat">
<%= @user.following.count %> following
</span>
</a>
</td>
<td>
<a href="<%= followers_user_path(@user) %>">
<span id="followers" class="stat">
<%= pluralize(@user.followers.count, "follower") %>
</span>
</a>
</td>
</tr>
</table>
我的“show.html.erb”文件:
<table summary="Information about following/followers">
<tr>
<td class="main">
<h1><%= @title %></h1>
<% unless @users.empty? %>
<ul class="users">
<%= render @users %>
</ul>
<%= will_paginate @users %>
<% end %>
</td>
<td class="sidebar round">
<strong>Name</strong> <%= @user.name %><br/>
<strong>URL</strong> <%= link_to user_path(@user), @user %><br/>
<strong>Microposts</strong> <%= @user.microposts.count%>
<%= render 'shared/stats' %>
<% unless @users.empty? %>
<% @users.each do |user| %>
<%= link_to gravatar_for(user, :size => 30), user%>
<% end %>
<% end %>
</td>
</tr>
这里是我的关系数据库文件(如果它帮助):
class CreateRelationships < ActiveRecord::Migration
def self.up
create_table :relationships do |t|
t.integer :follower_id
t.integer :followed_id
t.timestamps
end
add_index :relationships, :follower_id
add_index :relationships, :followed_id
add_index :relationships, [:follower_id, :followed_id], :unique => true
end
def self.down
drop_table :relationships
end
end
我试图删除的迁移,并再次重新开始(也准备测试数据库),但仍然一无所获。
如果还有其他文件可以帮助我解决问题,请告诉我!这里
编辑
问题是我的用户模型。下面是编辑后的版本(相关部分):
class User < ActiveRecord::Base
attr_accessor :password
attr_accessible :name, :email, :password, :password_confirmation
has_many :microposts, :dependent => :destroy
has_many :relationships, :foreign_key => "follower_id",
:dependent => :destroy
has_many :following, :through => :relationships, :source => :followed
has_many :reverse_relationships, :foreign_key => **"followed_id"**,
:class_name => "Relationship",
:dependent => :destroy
has_many :followers, :through => :reverse_relationships, :source => :follower
之前,foreign_key被设置为“followed_ ID”
你说得对!问题出在我的用户模型中。谢啦! – Angel 2012-04-01 22:35:53
