所以这可能是重复的,但是我在修复它时遇到了很多问题。我是Rails的新手,所以它很容易成为小事。我正在制作锻炼日志,并能够在控制台中成功保存新数据,但是当我转到服务器时,它不起作用。
用户模型:
class User < ApplicationRecord
has_secure_password
has_many :workouts, dependent: :destroy
VALID_EMAIL_REGEX = /\A[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/i.freeze
validates :name, :email, presence: true
validates :email, format: { with: VALID_EMAIL_REGEX }, uniqueness: { case_sensitive: false }
end
锻炼模型:
class Workout < ApplicationRecord
validates :date, presence: true
belongs_to :user
has_many :exercises, dependent: :destroy
accepts_nested_attributes_for :exercises, allow_destroy: true, reject_if: proc{ |attr| attr['name'].blank?}
end
锻炼控制器(某些方法已删除):
class WorkoutsController < ApplicationController
before_action :require_login
def new
@workout = current_user.workouts.build(date: Date.today)
end
def create
@workout = current_user.workouts.build(workout_params)
if @workout.save
redirect_to workouts_path, notice: 'Workout was successfully created.'
else
@errors = @workout.errors.full_messages
redirect_to new_workout_path, notice: @errors
end
end
private
def workout_params
params.fetch(:workout, {}).permit(:date, exercises_attributes: %i[_destroy id name reps weight weight_unit hours minutes seconds])
end
end
_form(已删除练习的嵌套表格):
<div class="container-fluid">
<%= form_with(model: @workout, local: true, authenticity_token: true) do |form| %>
<%= hidden_field_tag :authenticity_token, form_authenticity_token -%>
<% if @workout.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(@workout.errors.count, "error") %> prohibited this workout from being saved:</h2>
<ul>
<% @workout.errors.full_messages.each do |message| %>
<li><%= message %></li>
<% end %>
</ul>
</div>
<% end %>
<div class="container-fluid align-items-center">
<form>
<div class="container-fluid">
<%= form_for @workout do |f| %>
<div class="form-group">
<h2><%= f.label :date %></h2>
<div style="font-size: 18pt"><%= f.date_field :date %></div>
</div>
<% end %>
</div>
<div class="actions" >
<%= link_to "Create Workout", workouts_path, :method => :post %>
<%= form.submit %>
</div>
</form>
</div>
<% end %>
</div>
如果您发现有任何问题或对尝试的方法有任何建议,请告诉我。我确实注意到,如果所有锻炼均以新方法完成,但不能单击按钮,则可以保存。我有两个提交按钮,因为我分别在每个按钮上进行了不同的测试。
预先感谢,如果您要我发布更多信息,请告诉我。

您已将<form>...</form>
标记手动添加到html中,位于此处:
<form>
<div class="container-fluid">
<%= form_for @workout do |f| %>
<div class="form-group">
<h2><%= f.label :date %></h2>
<div style="font-size: 18pt"><%= f.date_field :date %></div>
</div>
<% end %>
</div>
<div class="actions" >
<%= link_to "Create Workout", workouts_path, :method => :post %>
<%= form.submit %>
</div>
</form>
不要那样做。 form_for
为您创建表单标签。
