我在我的应用程序中实现了一个简单的 Rails 搜索。在我这样做的时候,我只需要完成工作,但是我确信我做的方式远非 DRY,所以任何关于如何改进它的建议都将不胜感激。我基本上想要一个搜索文本框,带有 4 个单选按钮,用户可以选择它们来选择他们想要搜索的内容。
我目前的指数:
<%= form_tag("/search", :method => "get") do %>
<%= label_tag(:q, "Search for Product Title:") %>
<%= text_field_tag(:q) %>
<%= submit_tag("Search Title") %>
<% end %>
<br>
<%= form_tag("/search", :method => "get") do %>
<%= label_tag(:d, "Search for Product Description:") %>
<%= text_field_tag(:d) %>
<%= submit_tag("Search Description") %>
<% end %>
<br>
<%= form_tag("/search", :method => "get") do %>
<%= label_tag(:a, "Search for Category Names:") %>
<%= text_field_tag(:a) %>
<%= submit_tag("Search Category Name") %>
<% end %>
<br>
<%= form_tag("/search", :method => "get") do %>
<%= label_tag(:i, "Search for ID Str:") %>
<%= text_field_tag(:i) %>
<%= submit_tag("Search ID Str") %>
<% end %>
<<results from search here>>
控制器:
class SearchController < ApplicationController
def index
if params[:commit] == "Search Title"
# Great, now lets figure out what sort of query we're after
@searchQuery_title = params[:q]
@resultsReceived_title = true
if
@sqlResults_title_published_size = Product.where("title like ? AND published like ?", "%" + params[:q] + "%", '1')
@sqlResults_title_size = Product.where("title like ? OR categories like ?", "%" + params[:q] + "%", "%" + params[:q] + "%")
@sqlResults_title = Product.where("title like ? OR categories like ?", "%" + params[:q] + "%", "%" + params[:q] + "%").page(params[:page]).per(200).order("published DESC")
end
else
@resultsReceived_title = false
@sqlResults_title = []
end
if params[:commit] == "Search Description"
# Great, now lets figure out what sort of query we're after
@searchQuery_descr = params[:d]
@resultsReceived_descr = true
if
@sqlResults_descr_published_size = Product.where("long_descr like ? AND published = ?", "%" + params[:d] + "%", '1')
@sqlResults_descr_size = Product.where("long_descr like ?", "%" + params[:d] + "%")
@sqlResults_descr = Product.where("long_descr like ?", "%" + params[:d] + "%").page(params[:page]).per(200).order("published DESC")
end
else
@resultsReceived_descr = false
@sqlResults_descr = []
end
if params[:commit] == "Search Category Name"
# Great, now lets figure out what sort of query we're after
@searchQuery_cat = params[:a]
@resultsReceived_cat = true
if
@sqlResults_cat_published_size = Product.where("category_names like ? AND published = ?", "%" + params[:a] + "%", '1')
@sqlResults_cat_size = Product.where("category_names like ?", "%" + params[:a] + "%")
@sqlResults_cat = Product.where("category_names like ?", "%" + params[:a] + "%").page(params[:page]).per(200).order("published DESC")
end
else
@resultsReceived_cat = false
@sqlResults_cat = []
end
if params[:commit] == "Search ID Str"
# Great, now lets figure out what sort of query we're after
@searchQuery_idstr = params[:i]
@resultsReceived_idstr = true
if
@sqlResults_idstr_published_size = Product.where("id_str like ? AND published = ?", "%" + params[:i] + "%", '1')
@sqlResults_idstr_size = Product.where("id_str like ?", "%" + params[:i] + "%")
@sqlResults_idstr = Product.where("id_str like ?", "%" + params[:i] + "%").page(params[:page]).per(200).order("published DESC")
end
else
@resultsReceived_idstr = false
@sqlResults_idstr = []
end
# Render the page when we're done.
respond_to do |format|
format.html
end
end
end
也可以做一个 Product.where("title like ? OR categories like ? AND published = ? ", "%" + params[:q] + "%", "%" + params[:q] + " %", '1' ).page(params[:page]).per(200).order("已发布 DESC")
