Question

我有两个模型“ activity_templates”和“ activity”。我想在activity_template索引上创建一个链接以创建一个新的活动。我想将activity_template参数发送到活动表单。我想在新的活动表单上自动填写activity_template字段。

我不知道如何在索引页上传递参数。

我认为链接有问题。

链接：

<div class="box">
  <div class="box-header">
    <h3 class="box-title">Activities</h3>
    </div>
    <div class="box-body table-responsive no-padding">
      <table class="table table-bordered">

        <tbody>
          <% @activity_templates.each do |activity_template| %>
            <tr>
              <td><a href="<%= new_app_activity_path(activity_template_id: @activity_template) %>"><%= activity_template.name %></a></td>
            </tr>
          <% end %>
        </tbody>
      </table>
      <div class="text-right">
        <%= will_paginate @activity_templates %>
      </div>
  </div>
</div>

URL：

http://localhost:3000/app/activities/new

表格：

<%= simple_form_for([:app, @activity]) do |f| %>
  <%= f.error_notification %>

  <div class="form-inputs">
    <div class="row">
      <div class="col-md-6">
        <%= f.association :resident, label_method: :full_name, prompt: "Choose a resident", collection: Resident.order(:first_name), selected: @resident.id %>
      </div>
      <div class="col-md-6">
        <%= f.association :activity_template, collection: ActivityTemplate.order(:name).pluck(:name, :id), prompt: "Choose an activity template", selected: @activity_template.id    %>
      </div>
      <div class="col-md-6">
        <%= f.input :published_status, collection: ['Draft', 'Final'], default: 'Draft' %>
      </div>
      <div class="col-md-6">
        <div class="form-group">
          <label>Author</label>
        <input class="form-control" type="text" placeholder="<%= @current_user.full_name %>" readonly value="<%= @activity.author.try(:full_name) %>">
        </div>
      </div>
    </div>
    <%= f.input :data %>


  </div>

  <div class="form-actions">
    <%= f.button :submit %>
  </div>
<% end %>

活动控制器：

  def new
    @activity = current_business.activities.new
    if params[:resident_id].present?
    @resident = Resident.find(params[:resident_id])
    end
    if params[:activity_template_id].present?
    @activity_template = ActivityTemplate.find(params[:activity_template_id])
    end
  end

我想将activity_template参数发送到活动表单。

在将@activity_template迭代为activity_template时，应在链接中将@activity_templates更改为activity_template。

<td><a href="<%= new_app_activity_path(activity_template_id: activity_template) %>"><%= activity_template.name %></a></td>

现在，您应该在activity_template_id中看到url的值

http://localhost:3000/app/activities/new?activity_template_id=value

由于您已经在params[activity_template_id]中捕获了new，其余部分现在应该可以工作了。我也建议使用link_to

<%= link_to activity_template.name, new_app_activity_path(activity_template_id: activity_template) %>

使用参数在简单表单上自动填写字段
