Subject: Re: generate _update body using _show function

Unfortunately templates can only be a static string and not a function?

{
 "validate_doc_update":"function(n,o,u){if(!n['_id'])throw({forbidden:'no
_id'})}",
 "updates":{
  "post":"function(doc,req){
   for(i in req.form)doc[i]=3Dreq.form[i]
   return [doc,{headers:{'Content-Type':'text/html'},body:this.innerHTML(do=
c)}]
  }"
 },
 "shows":{"html":"function(doc,req){return
{headers:{'Content-Type':'text/html'},body:this.innerHTML(doc)}}"},
 "filters":{"design":"function(doc,req){return
'_design/'=3D=3D=3Ddoc._id.substr(0,8)}"},
 "innerHTML":"function(doc){return '\
<label>adress:</label>  <input name=3D\"adress\"
value=3D\"'+doc.adress+'\"/><br/>\\n\
<label>city:</label>    <input name=3D\"city\"
value=3D\"'+doc.city+'\"/><br/>\\n\
<label>country:</label> <input name=3D\"country\"
value=3D\"'+doc.country+'\"/><br/>\\n\
<label>phone:</label>   <input name=3D\"phone\"
value=3D\"'+doc.phone+'\"/><br/>\\n\
<label>email:</label>   <input name=3D\"email\"
value=3D\"'+doc.email+'\"/><br/>\\n\
<input name=3D\"_id\"  value=3D\"'+doc._id+'\"  type=3D\"hidden\"/>\\n\
<input name=3D\"_rev\" value=3D\"'+doc._rev+'\" type=3D\"hidden\"/>\\n\
<img id=3D\"picture\" src=3D\"/users/'+doc._id+'/picture.png\"/>'
 }"
}

PS syntax debugging design docs in couch db is !!!!!! because it does
not show the the character the parser did not like.
