ruby - Best way to access the values of a nested hash -

-

here hash:

{"funds"=>   {"0"=>     {"sector"=>"6555",      "fund_id"=>"4308",      "percent"=>"20.0",      "fund_distribution_id"=>"315304"     }   } }

how values sector, fund_id etc?

if following undefined method '[]' nil:nilclass because it's looking 'sector' key of '0'

params[:funds].each_with_index |f, index|     puts f[index]['sector'] end

if 

x = {"funds"=>       {"0"=>         {"sector"=>"6555",           "fund_id"=>"4308",           "percent"=>"20.0",           "fund_distribution_id"=>"315304"         }       }     }

, can value of sector , fund_id by

  x["funds"]["0"]["sector"]   x["funds"]["0"]["fund_id"]

python - jinja2: TemplateSyntaxError: expected token ',', got 'string' -

-
i new jinja2 , having issue using python regular expression (re). in following code bold lines have error string in them. {% block content %} <div class="container"> {% l in lines %} {% if re.search(r"error", l) %} {# <<< throws error #} <b> {{ l }} </b> {% else %} {{ l }} <hr> {% endif %} {% endfor %} </div> {% endblock %} the re.search above throws following error: jinja2.exceptions.templatesyntaxerror templatesyntaxerror: expected token ',', got 'string' raw python code not supported in jinja2 template syntax. {% if re.search(r"error", l) %} replace line with {% if "error" in l %} can fix problem. if logical condition more complicated, should consider defining own custom filters (which can call python code) or complicated things in view layer. go check global namespace .

Qt4: how to send QString inside a struct via QSharedMemory -

-
i have struct struct control_data{ int column_number; qstring cell; }; i need send thread of qsharememory. read can't because qstring contains pointers inside. other ways? you have serialize struct byte array. can convert qstring const char* this: mystring.tostdstring().c_str(); but serializing qstring should work. the first step serialize struct qdatastream using qt, example here . then once struct can read , written can pass shared memory. a complete example of using qsharedmemory can found here . here relevant code: // first, test whether shared memory segment attached process. // if so, detach if (sharedmem.isattached()) { sharedmem.detach(); } ... qbuffer buffer; buffer.open( qbuffer::readwrite ); qdatastream out( &buffer ); out << youstruct; int size = buffer.size(); // size of int + size of qstring in bytes if ( !sharedmem.create( size ) ) { return; } // write shared memory sharedmem.lock(); char *to = (char*...
