javascript - grabbing individual document in meteor template helper -

i trying access individual document within #each in meteor can mark it. if user clicks on content want run logic on document. example:

{{#each document}} <div>   {{text}}   {{did_i_read_the_doc}} </div> {{/each}} 

and want {{did_i_read_the_doc}} show "yes" or "no" depending on whether marked in collection. in template helper want like

template.documents.helpers({   did_i_read_the_doc: function() {     //what goes here?     if (thisindividualdocument.contains(meteor.userid() in "readby")       show "yes" in html     else       show "no" in html   } 

i'm not sure how access individual mongo document in helpers wrapped in each block. i'm used logic of returning of documents in helper documents: function() { return documents.find({}) }

but how define helper function gets individual document? in final run of things want able click document , mark read, notification, , have shows saying "already read" or "unread" depending.

i figured out right after posted.

in helper method can use

my: function() {   if(this.field)     //do 

so 'this' grabs individual document.

edit: example solve specific case

did_i_read_the_doc: function() {   if(this.read) {     return "yes"   }   else {     return "no"   } }
