Adding new fields to Sample

Technical Questions and Answers
1

Hi everyone, I am looking to add new fields to Sample, by developing a custom_lims add on to modify Sample and Patient fields. The problem is I cannot access ISample or Sample (commented below). Can someone who went through this help me? I am working with docker image of 2.x.

extender.py ----->
from zope.interface import implements
from zope.component import adapts
from plone.app.content.interfaces import INameFromTitle
from bika.lims.content.sample import Sample # does not work
from bika.lims.interfaces import ISample # does not work
from senaite.core.interfaces import ISamples # does not work
from senaite.lims.content.sample import Sample # does not work
from archetypes.schemaextender.interfaces import ISchemaExtender, IBrowserLayerAwareExtender
from archetypes.schemaextender.interfaces import ISchemaModifier
from Products.Archetypes import atapi

from custom.lims.interfaces import ICustomLimsLayer # your browser layer

class SampleExtender(object):
implements(ISchemaExtender, IBrowserLayerAwareExtender)
adapts(ISample)
layer = ICustomLimsLayer
def init(self, context):
self.context = context
def getFields(self):
return [
atapi.StringField(
“SampleSource”,
required=False,
searchable=True,
schemata=“Sample”,
widget=atapi.StringWidget(
label=“Sample Source”,
description=“Enter the source of the sample”,
),
)
]

This is my code extender.py, the problem is that the add view no show the new field:

from zope.interface import implements
from zope.component import adapts

from archetypes.schemaextender.interfaces import ISchemaExtender
from archetypes.schemaextender.field import ExtensionField

from Products.Archetypes.public import TextField
from Products.Archetypes.public import TextAreaWidget

from bika.lims.interfaces import IAnalysisRequest

class ExtendedTextField(ExtensionField, TextField):
“”“Campo de texto extendido para SchemaExtender.”“”

class AnalysisRequestExtender(object):
“”“Extiende el esquema de AnalysisRequest añadiendo el campo ‘partidas’.”“”
adapts(IAnalysisRequest)
implements(ISchemaExtender)
# Definir el nuevo campo.
fields = [
ExtendedTextField(
‘partidas’, # nombre interno del campo
default=‘’, # valor por defecto
widget=TextAreaWidget(
label=“Partidas”, # etiqueta visible en el formulario
description=“Ingrese las partidas asociadas”,
rows=4, cols=40,
visible={‘view’: ‘visible’, ‘edit’: ‘visible’},
),
),
]

def __init__(self, context):
    self.context = context

def getFields(self):
    # Devolver los campos a insertar en el esquema
    return self.fields
