Database/Code solutions for model with dynamic data, using Symfony 2 with Doctrine -


i'm making application symfony2 , doctrine , i'm facing problem i've wondered it's never been issue until today: how handle dynamic data?

in application i'm developing there data might relational , relational database features might useful , other data structure can dynamic , don't care querying , indexing, long it's stored , linked other relational data, example:

  • a user linked other users through "friendship" relation
  • a user can create documents fields can changed dinamically type-wise , must linked user created them

the best way make example compare drupal, can create own content types , define fields inside each content type (but content of type have same data, though can dinamically changed without altering code)

i don't want use drupal though, application have in mind complicated drupal (probably -a lot- of tweaks, -a lot- of modules , code edits, rather avoid, might similar result drupal, rather start scratch using symfony bending drupal will, thought of gives me shivers).

back question. have started studying problem , thinking no-sql solution mongodb, after reading around bit felt needed direction point reasearch in particular when ended reading http://www.sarahmei.com/blog/2013/11/11/why-you-should-never-use-mongodb/ , scared me bit. haven't ended research yet post made me lose hope bit , made me decide ask here in advance, hoping maybe has faced problem , found working , tested solution (which i'd use rather making untested 1 myself). issue can split in 2 parts:

1) database

the solutions came with, still little knowledge, are:

  1. relational database (mysql or postgres, i'm thinking second since has json support) tables dynamic content have text/longtext/json (in case of postgres) field contain json object containing data
  2. drupal-like solution each field mapped new table (i don't it, i'm adding completeness sake)
  3. hybrid solution: relational data in relational database, dynamic data in no-sql database fields (say, user_id, foreign key like) connect 2 things
  4. full no-sql solution: use mongodb (but i'd reassured issues mentioned in post above), or else...i'm open suggestions (as long can used symfony , doctrine)

2) code

i haven't yet investigated code part since have adapt database solution i'll use, aware doctrine has odm handle data mongodb database. don't know if it's possibile use both orm , odm @ same time , make them communicate it.
in case of #1 shouldn't hard, doctrine create array data , i'll able retrieve through function.
issue might have forms regarding data, haven't investigated yet

i aware symfony 2 cmf project might ideas http://cmf.symfony.com/ after looking around bit felt needed directions on issue

so kept searching , found this: mix of mysql , mongodb in application hstore field got interest.
looking further have discovered extension add hstore support on doctrine , symfony https://github.com/intaro/hstore-extension , looks it's need.

in alternative can use jsonb (still postgres) looks powerful tool dynamic models, support being introduced in doctrine , can wait until then

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.

javascript - IE11 incompatibility with jQuery's 'readonly'? -

the code i'm running has no issues in firefox, or chrome. user typing 1 textbox, tabs next , can continue typing that. when run webpage on ie11, user tabs next textbox , can't type in. textbox has double-clicked before user can insert anything. i've googled , seems ie give problems when using older jquery (i.e. prefers 'prop' 'attr' ). in code below jquery's readonly keyword being used in way ie11 no longer recognise/accept? i assume issue readonly , removeclass('ignore') working expected. //when focus on textbox 1 $("#field1").focus(function() { //remove readonly property textbox 1 $('#field1').prop('readonly', false).removeclass('ignore'); //add readonly property other textboxes $('#field2, #field3, #field4') .prop('readonly', 'readonly').addclass('ignore').val(''); }); i'm using jquery 2.1.3 ...
