I need render different show pages for my blog posts.
I have 3 different categories : themes, snippets, projects.
Each blog post must related with those three categories.
If anyone click post(assume related category is snippets), it display in different show...etc... It is same for other categories.
How it is possible with conditional statements.
you can make routes like:
resources :posts, except:[:show]
get 'posts/:id/cat/:category' , to:'posts#show', as: :show
you have to create partial for categories as follows:
app/views/posts/_themes.html.erb
app/views/posts/_snippets.html.erb
app/views/posts/_projects.html.erb
then in controller's show action.
controllers/posts_controller.rb
def show
@post = Post.find(params[:id])
@category = params[:category]
...
end
Then render that category in show page.
views/posts/show.html.erb
...
<%= render '#{@category}'%>
Just one show method and you can render different views conditionally and simple render works for you, you can use below code:
Just render with HTML file name if file is in same controller's view
if @post.theme?
render 'themes'
elsif @post.snippet?
render 'snippets'
else
render 'projects'
end
I would start with this, then refactor for avoiding repetition
categories_controller.rb
def themes
#@posts = Post.where(category_id: 1)
...
render layout: themes
end
def snippets
#@posts = Post.where(category_id: 2)
...
render layout: snippets
end
def projects
#@posts = Post.where(category_id: 3)
...
render layout: snippets
end
You can do something like this:
models/post.rb
def category
@category ||= ... #returns category name
end
controllers/post_controller.rb
def show
@post = Post.find(id)
@category = @post.category
...
end
views/posts/show.html.erb
...
<%= render "types/#{@category}" %>
...
Also you can render specified template from controller if you don't have any common parts for categories
You can use rails partial to achieve this:
to know more about partial refer Rails Partial
you can create partial for categories as follows:
app/views/categories/_themes.html.erb
app/views/categories/_snippets.html.erb
app/views/categories/_projects.html.erb
in show page of categories you can modify the show page as follows
class CategoriesController < ApplicationController
...
def show
...
render params[:category]
end
...
end
Now when you call show page pass a param category which denotes the type of category which you want to show
if you want to show category snippets then the params will be params[:category] = 'snippets' this will look for partial inside categories view.
