Rails从网址中删除某些参数

Question

What's the best method for removing certain params from a url? For example I'm looking to change:

www.testsite.com/blog?blog_id=1582

to

www.testsite.com/blog/1582

<%= link_to list.blog_name, blog_blogs_path(blog_id: list.blog_id) %>

Answer 1

1. I would double check your path as typically when linking to a direct item it is singular and not plural.
2. You just need the ID to be passed into the path

Example:

<%= link_to list.blog_name, blog_blog_path(list.blog_id) %>

Note the path is now: blog_blog_path (no s)

Answer 2

使链接成为变量，然后进行字符串替换

myString.gsub("?blod_id=", "/")

Answer 3

<%= link_to "blogs/index/#{list.blog_id}" %>
