I’m having some difficulty setting up Doctrine and am hoping some guru’s can give me a hand. If I try to save a MainEntity on its own, it works fine. However, if I add a “tag” to the tags collection of this entity, I get an error.<\/p>\n

Here is my info: I have entities that are similar to this<\/p>\n

Edit 1:<\/p>\n
Here are the lines from my SaveContent function<\/p>\n
public function saveContent($content)\n    {\n        $this->entityManager->persist($content);\n        $this->entityManager->flush();\n    }\n<\/code><\/pre>\n
Save content is pretty easy, however, to create the $content, I am doing the following<\/p>\n
    \n
  1. receive json that describes changes to the content object<\/li>\n
  2. check if the json I receive has an id. If so, I get the content object from the database. If not, I create a new content object<\/li>\n
  3. copy over the fields from the json object to my content object<\/li>\n
  4. call $content->tags->clear()<\/li>\n
  5. loop through each of the tags in the json object. These are just strings. I need to recreate $content->tags<\/li>\n
  6. \n
      \n
    1. See if there is a tag for this contentId and termName in the database. If so, add it to the tags collection. Done.<\/li>\n
    2. If not, see if there is a term in the database that matches the termName. If so, create a new tag, assign the term and content to it, and add it to tags. Done.<\/li>\n
    3. if not, create a new tag and a new term, assign the term and content to it, and add it to tags. Done.<\/li>\n<\/ol>\n<\/li>\n<\/ol>\n
      Doing a var dump shows that my $content object is as expected.<\/p>\n
      Edit 2: Solved<\/strong><\/p>\n
      My content object wasn’t as expected after all. I had added an array to the tags collection rather than a CG\\Tag.<\/strong><\/p>\n
        \n
      1. \n
        Just answering this question to close it. If anyone else has the same problem, maybe this can help.<\/p>\n
        My content object wasn’t as expected after all. I had added an array to the tags collection rather than a CG\\Tag. This resulted in the collection not being what Doctrine had expected hence the warning<\/p>\n
        \n
        Warning: spl_object_hash() expects parameter 1 to be object, array given<\/p>\n<\/blockquote>\n
        The warning was much more informative than the actual error.<\/p>\n<\/li>\n
      2. \n
        Just for practical purposes for Symfony2 developers: Take care to the difference between the addCategory<\/code> method and the setCategory<\/code> method!<\/p>\n
        \n<\/code><\/pre>\n<\/li>\n
      3. \n
        I had exaclty the same problem – also with tags (many tags related to many articles in DB).<\/p>\n
        I had the following instruction:<\/p>\n
                            foreach ($tags as $vv) {\n                        $tobj = $this->getDoctrine()\n                            ->getRepository(\"MainBundle:Tag\")\n                                ->findByTag($vv); \/\/ returns ARRAY of objects (= not wanted and not expected by Doctrine)\n                        \/\/...\n                        $artic->getTags()->add($tobj);\n<\/code><\/pre>\n
        And properly working code is:<\/p>\n
                            foreach ($tags as $vv) {\n                        $tobj = $this->getDoctrine()\n                            ->getRepository(\"MainBundle:Tag\")\n                                ->findOneByTag($vv); \/\/ returns one object\n                        \/\/...\n                        $artic->getTags()->add($tobj);\n<\/code><\/pre>\n
        (notice findONEby, not findby).<\/p>\n<\/li>\n<\/ol>\n

        I’m having some difficulty setting up Doctrine and am hoping some guru’s can give me a hand. If I try to save a MainEntity on its own, it works fine. However, if I add a “tag” to the tags collection of this entity, I get an error.
