php - Prevent Propel from inserting empty strings -

-

how can prevent propel orm inserting empty strings when column not set? 

create table user (     uid integer primary key auto_increment,     email varchar(255) not null unique,  -- no default value   ...   ) engine innodb ... ;

propel allows $user = new user(); $user->save();. have tried setting sql_mode doesn't help.

the correct way validator in schema , check using validate() method in code. here's example:

<database ...>   <table ...>     <!-- "required" attribute here sets db property -->     <column name="email" type="varchar" required="true" />     ...     <!-- adds unique index in db (but nothing in php code!) -->     <unique>       <unique-column name="email" />     </unique>     ...     <validator column="email">       <!-- validator rule makes $obj->validate() method fail on null -->       <rule name="required" message="the email required!" />       <!-- validator rule makes $obj->validate() method fail on empty string -->       <rule name="minlength" value="1" message="the email cannot blank!" />       <!-- add regular expression match email addresses here -->       <rule name="match" value="/regular expression/" message="please enter valid email address!" />       <!-- adds validation field unique before trying update db -->       <rule name="unique" message="that email address not unique!" />     </validator>   </table> </database>

then in presave() code this:

class user extends baseuser {   ...   public function presave(propelpdo $con = null) {     // object pass validations?     if (!$this->validate()) {       $errors = array();       // failed, go through each failure , capture message:       foreach ($this->getvalidationfailures() $failure) {         $errors[] = $failure->getmessage();       }       // throwing exception stop save() occurring       throw new invalidargumentexception(implode("||", $errors));     }      return true; // if here, go ahead , save   } }

in script call save() so:

... $user = new user(); try {   // try save (could fail)   $user->save();  } catch (invalidargumentexception $e) {   // have errors, split exception message each 1 separately   $errormessages = preg_split(/\|\|/, $e->getmessage());   // handle messages need }

How to calculate SNR of signals in MATLAB? -

-
i've encountered simple, yet fundamental problem on calculating snr: there several signals : s1 = original , pure clean signal without noise. n1 = white gaussian noise going added s1. s2 = s1 + n1 (the noisy signal before performing noise-reduction algorithm) s3 = noise-reduced signal (after performing noise reduction algorithm) n2 = s3 - s1 (the amount of noise after performing noise-reduction algorithm) now want compare snr before , after performing noise-reduction algorithm. which signals should consider snr_before!? s1/n1 or s2/n1 ? which signals should consider snr_after!? s3/n1 or s3/n2 ? which commands or functions should use in matlab in order compute snr_before , snr_after? thanks billion putting time on helping me. what know calculating snr before : snrbeforenoise = mean( signal .^ 2 ) / mean( noise .^ 2 ); and snr after : residual_noise = signal - noise_reduced_signal; snr_after = mean( signal .^ 2 ) / mean( residual_noise .^ 2...
