Hi
I'm trying to achieve the following piece of functionality.
I have a std::map with some keys, and a 2nd map with more keys.
If the 2nd map has a key from the first map then I want to iterate over the
values.
I've done the following which works but is a bit hackish. I created a tmp
variable that's assigned per loop so that it can be accessed from the
foreach. Ideally I'd want to get rid of the C++ section completely. I'm
guessing there probably is a way but I've just missed it
Any thoughts?
My Content looks like
// Fields
std::map<std::string,std::vector<std::string>> rms_fields;
std::map<std::string,std::vector<std::string>> xdb_fields;
// Tmp needed for cppcms foreach
std::vector<std::string> tmp_fields;
And tmpl file
<% foreach pair in rms_fields %>
<% item %>
<!-- If field is in both rms and
xdb then display across -->
<% if
(content.xdb_fields.find(pair.first) == content.xdb_fields.end()) %>
<tr><td><%= pair.first %>
</td>
<% foreach field in
pair.second %>
<% item %>
<td><%=
field %></td>
<% end %>
<% end %>
<td>-></td>
<td>XDB Trade</td>
</tr>
<% else %>
<!-- Display the RMS
fields first -->
<tr><td><%= pair.first %>
</td>
<% foreach field in
pair.second %>
<% item %>
<td><%=
field %></td>
<% end %>
<% end %>
<td>-></td>
<!-- Then the XDB fields,
I create a temporary variable in my content data structure in order to be
able to access it here
but really I was to
use it as a value in the "in" statement of the foreach below.
-->
<% c++ content.tmp_fields
= content.xdb_fields.find(pair.first)->second; %>
<% foreach field in
tmp_fields %>
<% item %>
<td><%=
field %></td>
<% end %>
<% end %>
</tr>
<% end %>
<% end %>
<% end %>
Thanks
Kind Regards
Ronnie
