c# - How should I be using repository? -


i'm trying implement repository, having trouble in application layer.

note:

  • transactionmodel nhibernate entity lazy loading
  • transaction application level object
  • mapper automapper, not relevant problem, no tag added this

i used have in application layer:

public transaction gettransaction(string itemname) {   using (var context = _sessionfactory.opensession())   {     var tran = context.get<transactionmodel>(itemname);     return mapper.map<transaction>(tran);   } }

which worked, since introducing repo clean app layer, problems mapping caused lazy loading nhibernate.lazyinitializationexception.

public transaction gettransaction(string itemname) {     var tran = _transactionrepository.getitem(itemname);     return mapper.map<transaction>(tran); }

clearly problem context has been closed time mapping. how should using repository in conjunction context? should make context in application layer , pass repo? this:

public transaction gettransaction(string itemname) {   using (var context = _sessionfactory.opensession())   {     var tran = _transactionrepository.getitem(context, itemname);     return mapper.map<transaction>(tran);   } }

this not affects mapping issue, other cases want read, modify , put transactionmodels

php - Calling a template part from a post -

i include iframe within post in wordpress. located inside content of post, meaning cannot in post template file, otherwise either before or after. i'd add facebook plugin within posts: <div id="socialwrap"><div class="fb-like" data-href="http://onlinearizonahomes.info" data-send="true" data-width="450" data-show-faces="true" data-font="arial"></div></div> i thinking of calling template part within post <?php get_template_part( 'social' ); ?> cannot use php within post without plugin (i'd avoid using plugin this). an alternative using javascript create html in post, seems unnecessary use of javascript. what best way add html within wordpress post? you can use shortcode. add functions.php function cudjex_fbshare( $atts, $content = null ) { global $post; $link = get_permalink($post->id); return '<div id="socialwrap...
