【问题描述】：

我有术语和短语模型，我正在添加嵌套资源。我想获取 Phraes_term 的 Term Id 以创建数据对

示例：术语 1 和短语 2。但是当你从 show.html.erb 术语中按下新按钮时，会出现错误

-->error :PhrasesTermsController#new is missing a template for request formats: text/html

form.html.erb -(phrases_term)。

<%= form_with(model: phrases_term, local: true) do |form| %>
  <% if pharases_term.errors.any? %>
    <div id="error_explanation">
      <h2><%= pluralize(pharases_term.errors.count, "error") %> prohibited this phrase from being saved:</h2>

      <ul>
      <% pharases_term.errors.full_messages.each do |message| %>
        <li><%= message %></li>
      <% end %>
      </ul>
    </div>
  <% end %>

  <div class="field">
    <%= form.label :ID %>
    <%= form.number_field_tag :ID %>
  </div>

  <div class="actions">
    <%= form.submit %>
  </div>
<% end %>

(phrases_term) -new.html.erb

<%= render 'form', phrases_term: @phrases_term %>

Phrases_terms_controller.rb

class PhrasesTermsController < ApplicationController
  before_action :authenticate_user!
  before_action :set_term

  def new
    @phrases_term = PhrasesTerm.new
  end

  def create
    @phrases_term = @term.phrases_term
    @phrases_term.user = current_user
    @phrases_term.save
    redirect_back(fallback_location: root_path)
  end
  
  private
  
  def phrases_term_params
    params.require(:phrases_term).permit(:term_id)
  end

  def set_term
    @term = Term.find(params[:term_id])
  end
end

routes.rb

resources :terms do
    resources :phrases_terms, only: [:create, :destroy, :new]
  end

（术语）显示.html.erb

<td><%= link_to 'New', new_term_phrases_term_path(@term) %></td>

(phrases_term).

_form.html.ebr
<%= form_with(model: phrases_term, local: true) do |form| %>
  <% if pharases_term.errors.any? %>
    <div id="error_explanation">
      <h2><%= pluralize(pharases_term.errors.count, "error") %> prohibited this phrase from being saved:</h2>

      <ul>
      <% pharases_term.errors.full_messages.each do |message| %>
        <li><%= message %></li>
      <% end %>
      </ul>
    </div>
  <% end %>

  <div class="field">
    <%= form.label :ID %>
    <%= form.number_field_tag :ID %>
  </div>

  <div class="actions">
    <%= form.submit %>
  </div>
<% end %>

(phrases_term)
 new.html.erb
<%= render 'form', phrases_term: @phrases_term %>

【解决方案1】：

这意味着您没有 app/views/phrases_term(s)/new.html.erb 文件。我不确定您是否已将文件命名为“phrases_term”或“phrases_terms”。

在正确的目录中创建一个，填充它，它会加载。
