如何解决搜索时出现Rails 5问题
我在这个问题上花了将近一天的时间,似乎无法弄清楚。我在index.html.erb页面上有一个表单,该表单可以进行搜索,看起来像这样:
<%= form_with(url: "/search",method: "get") do |f| %>
<%= f.label :Start_date %>
<%= f.date_select :date_out %>
<%= f.label :End_Date %>
<%= f.date_select :endDate %>
<br>
<p>Enter Report Type:</p>
<%= select_tag :reportType,options_for_select([['sale','sale'],['received','received'],['po','po'],['invoice','invoice']]) %>
<br>
<%= submit_tag("Show Report") %>
<% end %>
在我的控制器中,我有一个类似于以下内容的搜索操作:
class ItemInstancesController < ApplicationController
def search
# Converting the string params to a Date
startDate = Date.new(params["date_out(1i)"].to_i,params["date_out(2i)"].to_i,params["date_out(3i)"].to_i)
endDate = Date.new(params["endDate(1i)"].to_i,params["endDate(2i)"].to_i,params["endDate(3i)"].to_i)
# Getting the params from what the user submitted
reportType = params[:reportType]
if reportType == 'po'
# I have to do a search of the item_instances model to pull based on the date range of the date_out column
@item_instances = ItemInstance.search_for_records_by_date(startDate,endDate).order("po_number ASC")
format.html { render :search }
end
end
end
问题在于,当我点击表单时,我不会进入搜索页面。我可以看到我的参数很好。这是我在终端中点击“显示报告”按钮时看到的内容:
Started GET "/search?utf8=%E2%9C%93&%5Bdate_out(1i)%5D=2020&%5Bdate_out(2i)%5D=8&%5Bdate_out(3i)%5D=11&%5BendDate(1i)%5D=2020&%5BendDate(2i)%5D=8&%5BendDate(3i)%5D=11&reportType=po&commit=Show%20Report" for 10.9.0.201 at 2020-08-11 15:40:00 -0400

ArgumentError (too few arguments):

我也不知道为什么我的表单被处理为JS而不是HTML。当我提交表单时,网页上没有任何内容-意味着它保留在index.html.erb上。最后,我的路线如下:
Rails.application.routes.draw do
resources :item_instances
get '/search',to: 'item_instances#search'
resources :items
# Route to the home page
root 'home#index'
# For details on the DSL available within this file,see http://guides.rubyonrails.org/routing.html
end
模型是这样的:
create_table "item_instances",options: "ENGINE=InnoDB DEFAULT CHARSET=latin1",force: :cascade do |t|
t.integer "inv_number"
t.string "serial"
t.integer "po_number"
t.date "po_date"
t.date "invoice"
t.date "date_out"
t.decimal "cost",precision: 8,scale: 2
t.string "acro"
t.datetime "created_at",null: false
t.datetime "updated_at",null: false
t.bigint "item_id"
t.index ["item_id"],name: "fk_rails_6ea33fd9d0"
end
感谢您提供的任何帮助。
这是index.html.erb文件:
<p id="notice"><%= notice %></p>
<h1>Item Instances</h1>
<table>
<thead>
<tr>
<th>Inv number</th>
<th>Description</th>
<th>Serial</th>
<th>PO number</th>
<th>PO date</th>
<th>Invoice</th>
<th>Date Out</th>
<th>Cost</th>
<th>Acro</th>
<th colspan="3"></th>
</tr>
</thead>
<tbody>
<% @item_instances.each do |item_instance| %>
<tr>
<td><%= item_instance.inv_number %></td>
<td><%= link_to item_instance.item.description,edit_item_instance_path(item_instance)%></td>
<td><%= item_instance.serial %></td>
<td><%= item_instance.po_number %></td>
<td><%= item_instance.po_date %></td>
<td><%= item_instance.invoice %></td>
<td><%= item_instance.date_out %></td>
<td><%= item_instance.cost %></td>
<td><%= item_instance.acro %></td>
<td><%= link_to 'Show',item_instance %></td>
<td><%= link_to 'Edit',edit_item_instance_path(item_instance) %></td>
<td><%= link_to 'Destroy',item_instance,method: :delete,data: { confirm: 'Are you sure?' } %></td>
</tr>
<% end %>
</tbody>
</table>
<br>
<%= form_with(url: "/search",'invoice']]) %>
<br>
<%= submit_tag("Show Report") %>
<% end %>
<%= link_to 'New Item Instance',new_item_instance_path %>
这是search.html.erb页面:(我只希望页面此时显示标题)
<h1>Report Page</h1>
解决方法
form_with
的默认设置是远程发送表单。这就是为什么您看到Processing by ItemInstancesController#search as JS
的原因。如果将local: true
添加到表单中,则应在控制器中点击format.html
。您可以使用here阅读更多有关form_的信息。
您的format
必须在respond_to
块内
respond_to do |format|
format.html { render :search }
end
或者您可能只是逃脱
render :search
