将参数传递到自定义的Rails路线中
[英]passing params into a custom rails route
问题描述
I have struggled with this for a wee while now. 
我已经为此苦苦挣扎了一段时间。
there is the model 'custom pages' which belongs to 'leisure centres', a leisure centre can have many custom pages. 有一个属于“休闲中心”的“自定义页面”模型，一个休闲中心可以有许多自定义页面。
There is a defined custom route to show custom pages like so: 有一个定义的自定义路线来显示自定义页面，如下所示：
resources :centres,:path=>'leisure' do
...
member do
...
match "/page/:id" => "custom_pages#show", as: 'custom_page_path'
the desired url is something like this 所需的网址是这样的
/leisure/name_of_leisure_centre/page/377
I am trying to reach it by doing something like this... 我正在通过做这样的事情来达到目标...
=link_to custom_page.title, custom_page_path_centre_path(custom_page)
but this just gives me a url path 但这只是给我一个URL路径
/leisure/384/page/384
the last '384' is correct as it is the page id and where the first '384' should be the centre name should be there instead(which works fine if i use 'centre_path', everything works correctly there). 最后一个'384'是正确的，因为它是页面ID，而应该在第一个'384'应该是中心名称的地方（如果我使用'centre_path'可以正常工作，那么在那里一切正常）。
Here is the full block: 这是完整的块：
-borough.leisure_centres.each do |venue|
%span=venue.title
%li
=link_to "Overview", centre_path(venue)
%li
=link_to 'News', centre_news_index_path(venue)
%li
=link_to 'Facilities', facilities_centre_path(venue)
%li
=link_to 'Contact Us', new_centre_contact_form_path(venue)
-unless venue.venue_hire_content.nil?
%li
=link_to 'Hire', venue_hire_centre_path(venue)
-unless venue.virtual_tour.nil?
%li
=link_to 'Virtual Tour', tour_centre_path(venue)
-unless venue.custom_pages.nil?
- venue.custom_pages.each do |custom_page|
%li
=link_to custom_page.title, custom_page_path_centre_path(custom_page)
UPDATE: @Iceman's answer has got me closer, however the url is still correct 更新：@Iceman的答案使我更加接近，但是URL仍然正确
eg; 例如;
"/leisure/384/barking-sporthouse-and-gym/page/384"
should be 应该
"barking-sporthouse-and-gym/page/384"
update: added controller 更新：添加了控制器
def get_custompage
@custom_page = CustomPage.find(params[:id])
@centre = @custom_page.venue
@venue=@centre #because calling it @centre is pissing me off
#Sets standard Meta Content
unless @custom_page.nil?
@page_title = @custom_page.meta_page_title unless @custom_page.meta_page_title.nil? or @custom_page.meta_page_title == ""
@meta_description = @custom_page.meta_description unless @custom_page.meta_description.nil? or @custom_page.meta_description == ""
end
@main_class = "centres"
end

From your line in routes: 从路线中的路线：
resources :centres,:path=>'leisure' do
...
member do
...
match "/page/:id" => "custom_pages#show", as: 'custom_page_path'
It generates this path: 它生成此路径：
custom_page_path_centre GET /leisure/:id/page/:id(.:format)
Here if you see, it takes :id/page/:id which is causing Rails to put id at two places. 在这里，如果看到的话，它使用:id/page/:id ，这导致Rails将id放在两个位置。
You need to change your route to: 您需要将路线更改为：
resources :centres,:path=>'leisure' do
...
member do
...
...
end
resources 'custom_pages', path: 'page'
...
end
This should generate one of the routes like this: centere_custom_page_path pointing to: CustomPages#show . 这将生成以下路由之一： centere_custom_page_path指向： CustomPages#show 。
Then you can change view to this: 然后，您可以将视图更改为此：
-borough.leisure_centres.each do |venue|
%span=venue.title
%li
=link_to "Overview", centre_path(venue)
%li
=link_to 'News', centre_news_index_path(venue)
%li
=link_to 'Facilities', facilities_centre_path(venue)
%li
=link_to 'Contact Us', new_centre_contact_form_path(venue)
- unless venue.venue_hire_content.nil?
%li
=link_to 'Hire', venue_hire_centre_path(venue)
- unless venue.virtual_tour.nil?
%li
=link_to 'Virtual Tour', tour_centre_path(venue)
- unless venue.custom_pages.nil?
- venue.custom_pages.each do |custom_page|
%li
=link_to custom_page.title, centre_custom_page_path(centre_id: venue, id: custom_page.id)

This would work for you. 这将为您工作。
# routes.rb
match 'leisure/:centre_name/page/:id' => "custom_pages#show", as: 'custom_page'
# view file
= link_to custom_page.title, custom_page_path(centre_name: 'name_of_leisure_centre', id: 1)

You can use :param key if you don't want to change your routes structure. 如果不想更改路由结构，可以使用：param键。 In your routes.rb file: 在您的routes.rb文件中：
resources :centres, :path=>'leisure', :param=> :name_of_leisure_centre do
...
member do
...
get "/page/:id", to: "custom_pages#show", as: 'custom_page_path'
And then in your view file use: 然后在您的视图文件中使用：
= link_to custom_page.title, custom_page_path_centre_path(name_of_leisure_centre: centre.name, id: custom_page)
Produced 'href' would be 产生的“ href”将是
leisure/leisure_name/page/999
