Question

我尝试了这个form_for标记的每个配置，告诉它发布表单，但它会继续发布一个GET请求，其中包含我在post请求中需要的参数。以下是视图中的表单：

dash.html.erb：

<ul class = "new-offer-form" id = "new-offer-form">
    <form class="form-inline">

    <%= form_for(@offer, url: offers_create_path(@offer), method: :post, :html => {:class => "form-inline"}) do |f|%>
        <%= render 'shared/error_messages', object: f.object %>
        <div class="form-group">
            <li class = "offer-item"> <%= f.text_field :category %> </li>
        </div>
        <div class="form-group">
            <li class = "offer-item"> <%= f.text_field :plan_name %> </li>
        </div>
        <div class="form-group">
            <li class = "offer-item"> <%= f.text_field :price %> </li>
        </div>
        <div class="form-group">
            <li class = "offer-item"> <%= f.text_field :rate %> </li>
        </div>
        <div class="form-group">
            <li class = "offer-item"> <%= f.submit "Add new service plan", id: "new_link" %> </li>
        </div>

    <% end %>
</form>

这是控制器代码：

def dash
    @offer = current_user.offers.build()
    @offers = current_user.offers
    respond_to do |format|
      format.html
      format.json {render :json => @offer}
end

端

def create
    @user = current_user
    @offer = @user.offers.build(offer_params)

    if @offer.save
       flash[:success] = "Service plan added"
    else
       render 'offers/dash'
   end
end

这是在提交表单后出现在服务器日志中的内容：

Started GET "/offers/dash?utf8=%E2%9C   %93&authenticity_token=42V3KL6EB9BBE4h7LQbMIR44MZLq2KisKtgA6gh9dMBer5tewe%2     BUEWzZ0t0MG49IdisczNPz0PMtnUHSAxdf3A%3D%3D&offer%5Bcategory%5D=test&    offer%5Bplan_name%5D=hello&offer%5Bprice%5D=there&offer%5Brate%5D=world&commit=Add+new+service+plan" for 127.0.0.1 at 2017-04-12 22:16:25 -0400

我尝试将网址更改为＆＃39; offer / create＆＃39;哪些路线提供#cudate＆＃39;无济于事。有什么想法吗？

Answer 1

正如Dario在评论中所说，你实际上是在放置两个<form>标签，这些标签不是有效的HTML。

form_for默认为帖子（因此您不需要：method =＆gt;：post）。默认情况下，基本的html <form>代码是get，这就是您看到Get请求的原因。

并且，如果您要进行标准create操作并且已在路线中定义。

resources :offers

然后这将是form_for行

<%= form_for(@offer, :html => {:class => "form-inline"}) do |f|%>

rails 5 form_for（post method）发出get请求
