Question

I am solving situation about printing data from array via each loop.

in my controller

@dost_arr = ["aaab", "bbb", "ccc"]

in view

                <% @dost_arr.each do |i| %>
                <%='<tr class="show_lines">'.html_safe%>
                    <%='<td colspan="2">x'+ (link_to i, request.request_uri+'&d=0')+'</td>'%>
                <%='</tr>'%>
            <%end%>

But this generate me something like this

<td colspan="2">x<a href="/hledani/index?utf8=%E2%9C%93&amp;n

as source code, so I see in browser and not own data from array formatting into table…

Can anyone help me, please, what I am doing wrong?

Thank you

Why do you put html code inside ruby code? Use something like this:

<% @dost_arr.each do |i| %>
    <tr class="show_lines">
       <td colspan="2">x + <%= (link_to i, request.request_uri+'&d=0')+'%> </td>
    </tr>
<% end %>
