check if the type of the input is in SequenceType database or not

[deming7h777]

There are another name for molecule_type : ('nucl',Nucleotide'), ('prot','Peptide')
need to identify the input to these two type

[deming7h777]

class BlastDb(models.Model):
    objects = BlastDbManager()
    organism = models.ForeignKey(app.models.Organism)
    type = models.ForeignKey(SequenceType)
    # fasta_file = models.FileField(upload_to='blastdb') # upload file
    fasta_file = FileBrowseField('FASTA file path', max_length=200, directory='blast/db/', extensions='FASTA', format='FASTA')
    title = models.CharField(max_length=200, unique=True, help_text='This is passed into makeblast -title') # makeblastdb -title
    description = models.TextField(blank=True)  # shown in blast db selection ui
    is_shown = models.BooleanField(default=None, help_text='Display this database in the BLAST submit form') # to temporarily remove from blast db selection ui
    # sequence_count = models.PositiveIntegerField(null=True, blank=True)  # number of sequences in this fasta

In the progress of going through the BlastDb script I found out that one of the field 'type' in our model did not name correctly, it was the key word reserved by python itself.
