嗨,我目前正在制作一个用于上传图片的网络应用程序。有用户、相册和照片。当我尝试编辑用户的个人资料信息时,我无法弄清楚发生了什么。它告诉我在 UsersController#update 中有一个未定义的方法 'album' NoMethodError ,但我什至没有在我的 #update 操作中调用专辑。
def update
respond_to do |format|
if current_user.update_attributes(params[:user])
format.html { redirect_to current_user, notice: 'User successfully updated.'}
format.json { render json: current_user, status: :created, location: current_user }
else
format.html { render action: 'edit' }
format.json { render json: current_user.errors, status: :unprocessable_entity }
end
end
end
该错误特别是在我的更新操作的第 2 行和第 3 行。这是错误:
app/controllers/users_controller.rb:45:in 'block in update'
app/controllers/users_controller.rb:44:in
更新'`
有谁知道这到底是怎么回事?
为用户编辑表单
<%= form_for(@user) do |f| %>
<div class="formhold">
<div class="field">
<% if @user.profilepic? %>
<%= image_tag @user.profilepic.url %>
<% end %>
<%= f.label :profilepic, "Profile Picture" %>
<%= f.file_field :profilepic %>
</div>
<div class="field">
<%= f.label :name %>
<%= f.text_field :name %>
</div>
<div class="field">
<%= f.label :email %>
<%= f.text_field :email %>
</div>
<div>
<%= f.submit 'Submit', :class => 'submitbutton' %>
</div>
<% if @user.errors.any? %>
<div id="error_exp">
<h2><%= pluralize(@user.errors.count, "error") %> occurred.</h2>
<ul>
<% @user.errors.full_messages.each do |msg| %>
<li><%= msg %></li>
<% end %>
</ul>
</div>
</div>
<% end %>
<% end %>
<%= link_to "Back", user_path(@user) %>
