Q: How to display all database data to a html table in ruby on rails? I am new to Ruby on Rails. I am struggling with fetching all the data from the database to a html table. This is the controller that fetches the data from the db and pass it to a view. @result = Result.all and this is the view:

Name <%= @result.name %>

Address <%= @result.address %>

Contact No. <%= @result.contactno %>

Age <%= @result.age %>

Gender <%= @result.gender %>

Date <%= @result.date %>

A: You can do this by looping through all of the results:

<% @result.each do |res| %>
• <%= res.name %>
<% end %>

To use the index of the iteration, you can use the index operator:

<% @result.each_with_index do |res,index| %>
• <%= res.name %>
<% end %>

A: If you have more than one result, it's recommended that you use a method to loop through the result set:

<% @results.each do |result| %>
• <%= result.name %>
• <%= result.date %>
• <%= result.gender %>
• <%= result.age %>
<% end %>

or, alternatively, use a <% @results.each do |result| %> block in your view. A: In short, display it in a table, like this: - @results.each do |row| - row.each do |attribute| - puts attribute.to_s That will display each row, and each attribute in the table. A: Create view like this and run <% @result.each do |result| %> <% end %>

<%= result.name %>

<%= result.date %>

<%= result.gender %>

<%= result.age %>

And that will create a table like this : +-----+-----+-------+-------+-------+------+--------+ | name| date| gender| age | address| contact| city | +-----+-----+-------+-------+-------+------+--------+ | Joe | 03 | male | 30 | x | | Paris | +-----+-----+-------+-------+-------+------+--------+ Update: If you want to use form to update the rows, create view like this <% @result.each do |result| %> <% end %>

<%= result.name %>

<%= result.date %>

<%= result.gender %>

<%= result.age %>

And fill these inputs with their names, update button with id attribute_1_upadte so when click on that it will change values of input. Do not forget to set id for every input. I have updated code below for you: " name="name" type="text"> " name="date" type="text"> " name="gender" type="text"> " name="age" type="text"> Update After click Update your table will change like this : +-----+-----+-------+-------+-------+------+--------+ | name| date| gender| age | address| contact| city | +-----+-----+-------+-------+-------+------+--------+ | Mike| 05 | male | 30 | x | | Paris | +-----+-----+-------+-------+-------+------+--------+ Update: (if you want to fetch all your results without form) <% @result.each do |result| %> <% end %>

<%= result.name %>

<%= result.date %>

<%= result.gender %>

<%= result.age %>

After click update you will get table result like this : +-----+-----+-------+-------+-------+------+--------+ | name| date| gender| age | address| contact| city | +-----+-----+-------+-------+-------+------+--------+ | Mike| 05
