如何将此表单的结果提交给方法？

I get a NoMethodError when submitting this form, I've no idea how to get it to work. It's just a password reset form though the Devise gem, and trying the @user.send_reset_password_instructions in the console works just fine.

我在提交此表单时收到NoMethodError,我不知道如何让它工作。它只是一个密码重置形式,通过Devise gem,并在控制台中尝试@ user.send_reset_password_instructions工作得很好。

Here's the form in my view:

这是我视图中的表单:

<%= form_tag reset_password_path(:email), :id => 'forgotten_password' do %>
  <%= email_field_tag :email, nil, :placeholder => 'Email address' %>
  <%= submit_tag "Reset password" %>
<% end %>

In my routes:

在我的路线:

get "/dashboard/reset_password/:email" => "docs#reset_password", :as => :reset_password

In my controller:

在我的控制器中:

def reset_password
  @user = User.where(:email => params[:email]).first
  @user.send_reset_password_instructions
end

Here's the error:

这是错误:

No route matches [POST] "/dashboard/reset_password/email"

3 个解决方案

#1

Your route needs to have the POST method in it, not GET. And it should be /email not /:email

你的路线需要有POST方法,而不是GET。它应该是/电子邮件不是/:电子邮件

post "/dashboard/reset_password/email" => "docs#reset_password", :as => :reset_password

#2

You defined your route to respond to GET requests, and your form is sending a POST request. Try changing the method of your route from get to post

您定义了路由以响应GET请求,并且您的表单正在发送POST请求。尝试更改路线从get到post的方法

#3

So, part one is to make your route a POST instead of a GET (as mentioned previously). Typically whenever you're sending data to the server and it's causing a change (like setting the reset password token on a user account and sending them an email) you use a POST.

因此,第一部分是使您的路由成为POST而不是GET(如前所述)。通常,只要您将数据发送到服务器并导致更改(例如在用户帐户上设置重置密码令牌并向其发送电子邮件),就可以使用POST。

Change your route to look like this:

将您的路线更改为如下所示:

POST "/dashboard/reset_password" => "docs#reset_password", :as => :reset_password

Note: I also dropped the :email part of the path. You don't really need that.

注意:我还删除了路径中的:email部分。你真的不需要那个。

Part two, you'll need to tweak your form a little. You don't need to pass the :email symbol to the path. I'm not actually sure what that will do for you in this case. You get the email in the params hash in the controller (params[:email]) because you've got an email field in your form.

第二部分,你需要稍微调整你的表格。您无需将:email符号传递给路径。在这种情况下,我真的不确定那会对你有什么影响。您可以通过控制器(params [:email])中的params哈希获得电子邮件,因为您的表单中有一个电子邮件字段。

Change your form to look like this:

将表单更改为如下所示:

<%= form_tag reset_password_path, :id => 'forgotten_password' do %>
  <%= email_field_tag :email, nil, :placeholder => 'Email address' %>
  <%= submit_tag "Reset password" %>
<% end %>

That should generate the POST form path '/dashboard/reset_password' in your form HTML. When the user clicks on the "Reset password" button on the page the :email field in the form will get submitted to you. Rails will stuff it into the params and your controller method 'reset_password' be able to read it just fine.

这应该在表单HTML中生成POST表单路径'/ dashboard / reset_password'。当用户点击页面上的“重置密码”按钮时,表单中的:email字段将提交给您。 Rails会把它塞进params,你的控制器方法'reset_password'能够很好地读取它。

You might also want to do some error catching in your controller method. The most common problem with email password reset is that there's a typo in the email and you won't be able to find the user. It's helpful to return a message to the user when that happens.

您可能还想在控制器方法中捕获一些错误。电子邮件密码重置最常见的问题是电子邮件中存在拼写错误,您将无法找到该用户。发生这种情况时,向用户返回消息会很有帮助。

Good luck!
