Related field mapping in MongoDB mapping file:

 /**
     * @MongoDB\Date
     */
    public $logDate;
/**
     * Get logDate
     *
     * @return @MongoDb\Date $logDate
     */
    public function getLogDate()
    {
        return $this->logDate;
    }

    /**
     * Set logDate
     *
     * @param  $logDate
     * @return self
     */
    public function setLogDate($logDate)
    {
        $this->logDate = $logDate;

        return $this;
    }

First of all, i ask 2 questions about this things.

• Why mongodb storing date data as an object/array ?
• How can i fix this shit ?

thanks for all interests.

Answer 1

logDate is an array because it contains the following properties date, timezone_type and timezone. No idea why MongoDB is doing that I have never really worked with it so I do not have an answer to that question. However, if you want to handle timezone information as well you can just format the date into ISO8601 and store that then cross reference the given timezone for the actual name of the timezone.

To fix the logDate issue you can just use it as an array e.g. logDate['date'] to get the actually date time.
