简单形式:从另一个控制器创建新记录
Simple Form: creating a new record from another controller
我有一个带有索引视图的主控制器,它的作用类似于搜索框,让用户可以通过 select 框查询第一个 Table 或第二个 Table。用户输入搜索词后,他将被重定向到第一个或第二个模型的索引页面,其中包含该模型的搜索结果。
每次提交带有搜索类型和搜索词的查询时,都必须创建搜索记录。但是,我不知道如何使用来自不同控制器的 simple_form 创建新的搜索对象,在这种情况下是 Home 控制器。
家庭控制器
def index
@find = Find.new
主页索引视图
= simple_form_for @find, url: finds_path, method: :post do |f|
= f.input :search_type, :collection => [['First', 'First'], ['Second', 'Second']]
= f.input :search_term
= f.button :submit
找到控制器
def new
@find = Find.new
end
def create
@find = Find.new(find_params)
if params[:search_type] == 'First'
redirect_to first_path
elsif params[:search_type] == 'Second'
redirect_to second_path
else
redirect_to root_path
end
end
private
def find_params
params.permit(:search_term, :search_type, :utf8, :authenticity_token,
:find, :commit, :locale)
# the params seem to come from the Home controller so I added them just to see if they will go through :(
end
不保存。相反,它给出:
Started POST "/en/finds"
Processing by FindsController#create as HTML
Parameters: {"utf8"=>"✓", "authenticity_token"=>"..", "find"=>{"search_type"=>"First", "search_term"=>"Something"}, "commit"=>"Create Find", "locale"=>"en"}
Unpermitted parameter: :find
Redirected to http://localhost:3000/en
您需要保存,您只是在初始化属性..
@find = Find.new(find_params)
@find.save!
或
@find = Find.create!(find_params)
还有,强参数应该是
def find_params
params.require(:find).permit(:search_term, :search_type)
end
Unpermitted parameter: :find
你的find_params
应该只是
def find_params
params.require(:find).permit(:search_type, :search_term)
end
您应该使用 params[:find][:search_type]
访问 search_type
if params[:find][:search_type] == 'First'
redirect_to first_path
elsif params[:find][:search_type] == 'Second'
redirect_to second_path
else
redirect_to root_path
end
此外,我建议重命名 Find
模型,因为它与 ActiveRecord#FinderMethods
冲突
