用模態更改link_to

Question

我正在開展一個項目，人們可以在工作中雇用一個活動。 實際上他們只能“假設”但我不想添加他們可以為他們的應用程序添加價格的選項。

所以這是我的古代代碼[工作]：

<% if @current_user != @project.user %>
    <% if project_job.users.find { |user| user == current_user } %>
     <%= link_to "Retirer ma candidature", project_project_job_postulant_path(@project, project_job, project_job.postulants.find_by_user_id(current_user.id)), method: :delete, class:"btn btn-primary btn-prostate" %>
    <% else %>
     <%= link_to "Postuler", project_project_job_postulants_path(@project, project_job), method: :post, class:"btn btn-primary btn-prostate" %>
    <% end %>
  <% end %>

我想做這樣的事情：

<% if @current_user != @project.user %>
  <% if project_job.users.find { |user| user == current_user } %>
    <%= link_to "Retirer ma candidature", project_project_job_postulant_path(@project, project_job, project_job.postulants.find_by_user_id(current_user.id)), method: :delete, class:"btn btn-primary btn-prostate" %>
  <% else %>
    <div class="modal-content">
      <%= simple_form_for [@project, @project_job] do |f| %>
        <%= f.input :budget, required: true, autofocus: true, placeholder: "Budget moyen par personne. En Euros - €"%>
        <%= f.button :submit, value: "Add", class: "btn btn-primary" %>
      <% end %>
    </div>
  <% end %>
<% end %>

但我在autorisation上有一個錯誤，也許你可以幫我用simple_form_for切換這個link_to。

先感謝您。

嘗試將表單更改為 -

<%= simple_form_for [@project, project_job, project_job.postulants.build] do |f| %>
 <%= f.hidden_field :user_id, current_user.id %>
 <%= f.input :budget, required: true, autofocus: true, placeholder: "Budget moyen par personne. En Euros - €"%>
 <%= f.button :submit, value: "Add", class: "btn btn-primary" %>
<% end %>
