asp.net mvc - NerdDinner difficulties -

-

i'm having problem create method of nerddinner tutorial, btw.

as can see here http://nerddinnerbook.s3.amazonaws.com/part5.htm in create method, removed id field of aspx page.

i did too, cannot add dinners because primary key violation.

how nerddinner controlling ids of each dinner? revised tutorial , not see references identity fields on sql database.

i created method me highest id in table:

    public int gethighestdinnerid()     {         int resultado = (from dinner in datacontext.dinners                          select dinner.dinnerid).max();         return resultado;     }

which not work either.

any thoughts?

thank you

heya, i'm speculating here assume primary key should have auto-generated value property set true don't have explicitly set it, gets generated on insert. should able configure within dbml.

edit: looked through nerddinner tutorial , if @ step 2, talks setting id column identity column value auto-generated want configure it.

(or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
