hi,<br />
<br />
I am wondering if there is smart/elegant ways of checking nil object.<br />
<br />
I have this in controller:<br />
<br />
&nbsp;@attending_ip = AttendingIp.find_by_sql(&quot;S<wbr />ELECT .....&quot;)<br />
<br />
In view:<br />
<br />
&lt;% if @attending_ip != nil%&gt;<br />
&lt;% @attending_ip.each do |u| &nbsp;%&gt;<br />
...<br />
...<br />
<br />
&lt;%if u.admit_date != nil%&gt;&lt;%= u.admit_date.to_formatted_<wbr />s(:my_form<wbr />at_0) &nbsp;%&gt;&lt;%end%&gt;<br />
<br />
...<br />
...<br />
<br />
I am checking &nbsp;whether u.admit_date is nil otherwise, it throws error message since admit_date can be null. So, do I always have to check for all the columns? Are there better ways of doing this?<br />
<br />
thx,<br />

hi,

I am wondering if there is smart/elegant ways of checking nil object.

I have this in controller:

 @attending_ip = AttendingIp.find_by_sql("SELECT .....")

In view:

<% if @attending_ip != nil%>
<% @attending_ip.each do |u|  %>
...
...

<%if u.admit_date != nil%><%= u.admit_date.to_formatted_s(:my_format_0)  %><%end%>

...
...

I am checking  whether u.admit_date is nil otherwise, it throws error message since admit_date can be null. So, do I always have to check for all the columns? Are there better ways of doing this?

thx,


checking nil object

Ruby is an open-source dynamic object-oriented interpreted language that supports multiple programming frameworks including functional, object oriented and imperative. It also has a dynamic type system and automatic memory management. Ruby focuses on simplicity and productivity. Ruby's market share spiked due to Ruby on Rails, a model-view-controller (MVC) framework for building web applications.
