I have this table
t.string "first_name"
t.string "last_name"
t.integer "age"
t.string "email"
I am using some search functionality where I search for a Barber by first_name .
Then I am displaying it and whatever else is similar to the input.
This is my current view (search.html.erb)
<h1>searches</h1>
<%= #barbers.each do |barber|%>
<%= barber.first_name%><br>
<%end%>
Very plain and simple and this is how it looks.
I obviously don't want to keep it like this.
I want it to look like this , the way I have it in my index.html.erb
<table class="table table-dark table-striped">
<thead>
<tr>
<th scope="row">First name</th>
<th scope="row">Last name</th>
<th scope="row">Age</th>
<th scope="row">Email</th>
<th scope="row">User ID</th>
<th colspan="3"></th>
</tr>
</thead>
<tbody>
<% #barbers.each do |barber| %>
<tr>
<td><%= barber.first_name %></td>
<td><%= barber.last_name %></td>
<td><%= barber.age %></td>
<td><%= barber.email %></td>
<td><%= barber.user_id %></td>
<td><%= link_to 'Show', barber %></td>
<td><%= link_to 'Edit', edit_barber_path(barber) %></td>
<td><%= link_to 'Destroy', barber, method: :delete, data: { confirm: 'Are you sure?' } %></td>
</tr>
<% end %>
</tbody>
</table>
I am just confused on how to write the code since I am searching for each. #barbers.each do |barber|
Here is what I done...
<h1>searches</h1>
<table class="table table-dark table-striped">
<thead>
<tr>
<th scope="row">First name</th>
<th scope="row">Last name</th>
<th scope="row">Age</th>
<th scope="row">Email</th>
<th scope="row">User ID</th>
<th colspan="3"></th>
</tr>
</thead>
<tbody>
<% #barbers.each do |barber| %>
<tr>
<td><%= barber.first_name %></td>
<td><%= barber.last_name %></td>
<td><%= barber.age %></td>
<td><%= barber.email %></td>
<td><%= barber.user_id %></td>
</tr>
<% end %>
</tbody>
</table>

I am trying to create a spreadsheet on index page to display items with checkbox and if validated - the checkbox will be disabled so that people won't mis-ticked it.I was wondering should i do it with controller or the view? thanks : can you help?
In app/views/scooties_coupons/index.html.erb
<table class="table table-hover">
<h1>Scooties Coupons</h1>
<%= form_with(url: validate_coupons_path, method: 'patch') do |f| %>
<table>
<thead>
<tr>
<th>Valid</th>
<th>Coupon</th>
<th>Redeemed</th>
<th>First name</th>
<th>Surname</th>
<th>email</th>
<th>occupation</th>
<th>validation</th>
<th colspan="3"></th>
</tr>
</thead>
<tbody>
<% #scooties_coupons.each do |scooties_coupon| %>
<tr>
<td>
<%= fields_for('scooties_coupons[]', scooties_coupon) do |cf|
cf.check_box(:validated)
end %>
</td>
<td><%= scooties_coupon.coupon %></td>
<td><%= scooties_coupon.redeemed %></td>
<td><%= scooties_coupon.first_name %></td>
<td><%= scooties_coupon.surname %></td>
<td><%= scooties_coupon.email %></td>
<td><%= scooties_coupon.occupation %></td>
</tr>
<% end %>
</tbody>
</table>
<%= f.submit %>
<% end %>
<br>
</table>
in app/controllers/scotties_coupons_controller.rb:
def set_valid_coupons
to_valid = params[:scooties_coupons].select do |id, attrs|
attrs[:validated] == '1'
end
to_not_valid = params[:scooties_coupons].reject do |id, attrs|
attrs[:validated] == '1'
end
ScootiesCoupon.transaction do
ScootiesCoupon.where(id: to_valid.keys, validated: false).update_all(
validated:true)
ScootiesCoupon.where(id: to_not_valid.keys, validated: true).update_all(
validated:false)
end
redirect_to action: :index, notice: 'Validations updated'
end
you can do something like
<table class="table table-hover">
<h1>Scooties Coupons</h1>
<%= form_with(url: validate_coupons_path, method: 'patch') do |f| %>
<table>
<thead>
<tr>
<th>Valid</th>
<th>Coupon</th>
<th>Redeemed</th>
<th>First name</th>
<th>Surname</th>
<th>email</th>
<th>occupation</th>
<th>validation</th>
<th colspan="3"></th>
</tr>
</thead>
<tbody>
<% #scooties_coupons.each do |scooties_coupon| %>
<tr>
<td>
<% if true %>
SOMETHING HERE
<% else %>
<%= fields_for('scooties_coupons[]', scooties_coupon) do |cf|
cf.check_box(:validated)
end %>
<% end %>
</td>
<td><%= scooties_coupon.coupon %></td>
<td><%= scooties_coupon.redeemed %></td>
<td><%= scooties_coupon.first_name %></td>
<td><%= scooties_coupon.surname %></td>
<td><%= scooties_coupon.email %></td>
<td><%= scooties_coupon.occupation %></td>
</tr>
<% end %>
</tbody>
</table>
<%= f.submit %>

I have used Ransack Gem,Rails 4.
roles_controllers.rb
def index
#q = Role.ransack(params[:q])
#roles = #q.result(distinct: true)
end
This is instance method in model(role.rb)
def user_count
self.users.count
end
This is my html table header(Roles/index.html.erb)
<table class="table table-bordered table-framed rb-usr-tbl">
<thead>
<tr>
<th><%= sort_link(#q, :name) %></th>
<th>Description</th>
<th><%= sort_link(#q,:role_users_user_count) %></th>
<th colspan="2">Actions</th>
</tr>
</thead>
<tbody class="role-index">
<% #roles.each do |role| %>
<tr>
<td><%= role.human_role %></td>
<td><%= role.description %></td>
<td><%= role.user_count %></td>
<td>
<%= link_to edit_role_path(role), :remote => true,:title => "Edit Role" do %>
<i class="icon-pencil7 rb-pencil"></i>
<% end %>
</td>
<td>
<%= link_to role, method: :delete,:title => "Delete Role", data: { confirm: 'Are you sure?' } do %>
<i class="icon-trash rb-trash"></i>
<% end %>
</td>
</tr>
<% end %>
</tbody>
</table>
There is relationship between user and role are One role has_many users.
Here i want to sort this count of users in asc and desc order but with this code it does not work.
Help me if you can.
Thanks
Ransack is very smart itself, try to change line
<th><%= sort_link(#q,:role_users_user_count) %></th>
to
<th><%= sort_link(#q, :users_count) %></th>
Explanation: In the variable #q you keep a Ransack query object on the model Role, if you call sort_link on #q it will apply users_count as "join users relation and order by users count".
In my costs table I have created a variable to calculate the rate multiplied by the hours and I can obtain my figure successfully. However, I need to calculate the total of each row at the end of my table. One of my fields are "total of all rows". What is the best course of action for this?
Any suggestions?
In my costs/index.html.erb file this is the code I currently have
<tbody>
<% #costs.each do |cost| %>
<tr>
<td><%= cost.mini_description %></td>
<td><%= cost.description %></td>
<td><%= cost.quantity %></td>
<td><%= cost.rate %></td>
<td><%= cost.total%><%=cost.cost_var%></td>
<td><%= cost.total_of_all_rows %></td>
<!--<td><%#= cost.job %></td>-->
<td><%= link_to 'Show', cost %></td>
<td><%= link_to 'Edit', edit_cost_path(cost) %></td>
<td><%= link_to 'Destroy', cost, method: :delete, data: { confirm: 'Are you sure?' } %></td>
</tr>
<% end %>
</tbody>
<thead>
<tr>
<th>Total of all rows</th>
</tr>
</thead>
I have fixed my code yet I am still not getting the desired result my total_of_all_rows is not adding up the sum of rate and quantity. My amended code is:
<tbody>
<% #costs.each do |cost| %>
<tr>
<td><%= cost.mini_description %></td>
<td><%= cost.description %></td>
<td><%= cost.quantity %></td>
<td><%= cost.rate %></td>
<td><%= cost.total%><%=cost.cost_var%></td>
<!--<td><%#= cost.job %></td>-->
<td><%= link_to 'Show', cost %></td>
<td><%= link_to 'Edit', edit_cost_path(cost) %></td>
<td><%= link_to 'Destroy', cost, method: :delete, data: { confirm: 'Are you sure?' } %></td>
</tr>
</tbody>
<thead>
<tr>
<th>Total of all rows</th>
</tr>
</thead>
<tr>
<td><%= cost.total_of_all_rows %><%=Cost.sum(:total) %></td>
</tr>
<% end %>
<tbody>
</tbody>
</table>
My migration for this table is
class CreateCosts < ActiveRecord::Migration
def change
create_table :costs do |t|
t.string :mini_description
t.string :description
t.string :quantity
t.string :rate
t.string :total
t.string :total_of_all_rows
t.references :job, index: true
t.timestamps
end
end
end
1)Don't store the total_of_all_rows in the databse as long as it is variable and you will have to update it with each new entry.
2)Delete column from migration.
3)In your view:
<tbody>
<% #costs.each do |cost| %>
<tr>
<td><%= cost.mini_description %></td>
<td><%= cost.description %></td>
<td><%= cost.quantity %></td>
<td><%= cost.rate %></td>
<td><%= cost.total%><%=cost.cost_var%></td>
<!--<td><%#= cost.job %></td>-->
<td><%= link_to 'Show', cost %></td>
<td><%= link_to 'Edit', edit_cost_path(cost) %></td>
<td><%= link_to 'Destroy', cost, method: :delete, data: { confirm: 'Are you sure?' } %></td>
</tr>
</tbody>
<thead>
<tr>
<th>Total of all rows</th>
</tr>
</thead>
<tr>
<td><%= #costs.sum(:total) %></td>
</tr>
<% end %>
<tbody>
If you still want to store the value:
class Cost < ActiveRecord::Base
after_save :update_totals
def update_totals
Item.all.each {|x| x.total_of_all_rows = Item.sum(:total)
end
end
here i have 2 simple model with one-many relation:
class Category < ActiveRecord::Base
attr_accessible :Name
has_many :items
class Item < ActiveRecord::Base
attr_accessible :Category_id, :Name, :Price, :Description
belongs_to :category
and I've a View to show info about Item like:
<table>
<tr>
<td class="field" style="width: 175px;"><b>Name:</b></td>
<td><%= #item.Name %></td>
</tr>
<tr>
<td class="field"><b>Price:</b></td>
<td><%= #item.Price%></td>
</tr>
<tr>
<td class="field"><b>Category: </b></td>
<td><%= Category.find(#item.Category_id).Name %></td>
</tr>
<tr>
<td class="field"><b>Description: </b></td>
<td><%= #item.Description %></td>
</tr>
</table>
It's work right. But here I've a question: Is there's another ways to call class Category 's attribute. Something like #item.category.Name which I try but didn't work ( undefined method "Name" for nil:NilClass)
Why do you have your attributes in camel case? Downcase them and change this:
<tr>
<td class="field"><b>Category: </b></td>
<td><%= Category.find(#item.Category_id).Name %></td>
</tr>
to this:
<tr>
<td class="field"><b>Category: </b></td>
<td><%= item.category.name %></td>
</tr>
It should work.
Perhaps a nil check would help, as described here.
<tr>
<td class="field"><b>Category: </b></td>
<td><%= #item.category.name unless #item.category.nil? %></td>
</tr>
How do I organize my items in a table
so that my row has lets say 4 columns, in my
foreach(var item in Model.Data)
{
<td>item.name</td>
}
How do I have item.name[i], item.name[i+1] so that I can fill out my column for the row?
I'm not clear on exactly what you're asking or what version of MVC or View Engine, but the general pattern of a table displaying a collection of objects is
<table>
<thead>
<tr>
<td>Name</td>
<td>Description</td>
<td>Hair Color</td>
</tr>
</thead>
<tbody>
<% foreach (var item in Model) { %>
<tr >
<td><%= Html.Encode(item.Name) %></td>
<td><%= Html.Encode(item.Description) %></td>
<td><%= Html.Encode(item.HairColor) %></td>
</tr>
<% } %>
</tbody>
</table>
