Django Blog post like feature
I want to make "like" feature for blog posts so that any user can like a post. I saw different approaches. In some they've made a model field "like", in some they've made a separate Like model and used the User and Post models as foreign keys in that. I'm also not sure about how to implement JavaScript in it. I mean how to call the methods or URLs. Hope you get it. It would be very helpful if anybody can explain how to do it. -

Configuration of bokeh + channels integration
I’m using the bokeh django-embed example and have a few questions about what these lines are doing / how to access them by url: document(“shape_viewer”, views.shape_viewer_handler), document(“sea_surface_with_template”, views.sea_surface_handler_with_template) versus: autoload("sea_surface", views.sea_surface_handler) As best as I can tell, if you make the autoload route, then it uses the autoloadjs consumer to bundle up the bokeh app with autoload.js and then the websocket consumer later serves it to the websocket connection? I’m lost about the DocConsumer though - also, for testing purposes I attempted to remove the: 'websocket': AuthMiddlewareStack(URLRouter(patterns)) from routing.py, however for some reason it expects to find a ‘sea_surface/ws’ route - where is this specified? Is it possible to change it to for instance look for the websocket at ‘sea_surface/wasdf’? Lastly, is it possible to do other things with the websocket connection to a session / can I access it anywhere? Thanks for any help! -

Django aggregation function in Hstore field

Django Select2Widget not getting styled properly with crispy forms
I'm using the django-select2 package to implement Searchable Select on a ForeignKey field. I was successful in getting the functionality to work by following the steps mentioned in the docs but I am having trouble with the styling. To render my form I use crispy-forms. All the other widgets get rendered properly except the Select2Widget. As can be seen in the above image, the height and width of the form element is not dynamic like other elements. HTML code generated: <div class=""> <select name="current_user" data-minimum-input-length="0" data-allow-clear="true" data-placeholder="" class="select2widget form-control django-select2" required id="id_current_user"> <option value=""></option> <option value="">---------</option> <option value="4" selected>Arpita</option> </select> </div> </div> <div id="div_id_device_admin" class="form-group"> <label for="id_device_admin" class=" requiredField"> Device admin<span class="asteriskField">*</span> </label> <div class=""> <select name="device_admin" data-minimum-input-length="0" data-allow-clear="true" data-placeholder="" class="select2widget form-control django-select2" required id="id_device_admin"> <option value=""></option> <option value="">---------</option> <option value="4" selected>Arpita</option> </select> </div> </div> This is how I set the widget in ModelForm. def __init__(self, *args, in_org, **kwargs): ... self.fields['current_user'].widget = Select2Widget() self.fields['current_user'].queryset = in_org.user_set.all() I feel this is mostly an issue with CSS styling and I am unable to figure out the issue. Any help would be greatly appreciated. -

Cant connect vnic through pyvomi
After a restore of a VMware VM through Veeam API, the Network adapter or vNic will not reconnect. When the VM gets a power off before the restore, the checkboxes for connect at powerOn get unchecked. My code runs tests afterwards, and because there is no connected vNic there is no IP address to check, thus my tests and with that the whole restoretask fail. This is my code. I tried to connect the Vnic before and after the poweron but both wont work. vo = VcenterAPIOperations(vdc_id=asset_obj.logical_switch.ive.datacenter.virtual_dc.id) power_on_result = vo.vm_power_on(vm_moid=asset_obj.moid, asset_id=asset_id) vnic_recon_result = vo.vm_reconnect_vnic(dvportgroup_moid=asset_obj.logical_switch.dvportgroup, vm_moid=asset_obj.moid) # Retrieve the VM hardware configuration and update the database vo.vm_update_hardware_config(asset_id=asset_id, task_id=task_id) return restore_result, power_on_result, vm_reconnect_vnic Where the vm_reconnect_vnic function is the following: def vm_reconnect_vnic(self, dvportgroup_moid, vm_moid): dvportgroup_obj = self._get_obj_by_moid(moid=dvportgroup_moid, folder_type='network', vim_type='dvportgroup') vm_obj = self._get_obj_by_moid(moid=vm_moid) for device in vm_obj.config.hardware.device: if isinstance(device, vim.vm.device.VirtualEthernetCard): nic_spec = vim.vm.device.VirtualDeviceSpec() nic_spec.operation = 'connect' nic_spec.device = device dvs_port_connection = vim.dvs.PortConnection() dvs_port_connection.portgroupKey = dvportgroup_obj.key dvs_port_connection.switchUuid = dvportgroup_obj.config.distributedVirtualSwitch.uuid nic_spec.device.backing = vim.vm.device.VirtualEthernetCard.DistributedVirtualPortBackingInfo() nic_spec.device.backing.port = dvs_port_connection vm_spec = vim.vm.ConfigSpec(deviceChange=[nic_spec]) task = vm_obj.ReconfigVM_Task(vm_spec) result = str(self.wait_for_task(task).info.state) return result Thanks in advance -

Django DATETIME_FORMAT incorrect (by one year) for specific dates
For a client I am storing event logs in a postgres database. Each event has a date that is stored as a timestamp with time zone in postgres. The date is automatically populated using Djangos' built in auto_now_add attribute in the model definition. In settings.py I have set the following: TIME_ZONE = 'UTC' USE_TZ = True DATETIME_FORMAT = 'd/m/o H:i:s' DATE_FORMAT = 'd/m/o' TIME_FORMAT = 'H:i:s' SHORT_DATE_FORMAT = 'd/m/o' SHORT_DATETIME_FORMAT = 'd/m/o H:i' I have lots of experience with this mechanism and it never caused problems until now. The client actually pointed out that there were a number of entries with a date lying in the future (impossible for event log). After checking the front-end as well as the admin I can verify that there are invalid dates e.g.(30/12/2020 and 31/12/2020) appearing (all invalid dates are in this range, other dates before and after are displaying correctly). When I check the database (Postgres) I can verify that the dates stored are actually both in 2019 having the following timestamp values: 2019-12-30 10:23:07.451674+00 and 2019-12-31 08:12:26.635693+00. The template in use in the frontend uses {{ log_item.date }} to display the date. What am I missing? Any hints appreciated. -

How to serve django and gatsby on single vhost?
I'm trying to deploy gatsby based frontend with django based backend under a single domain. It will rely on Apache and mod_wsgi. In a perfect world it should work as following: https://my-domain.com/ - gatsby frontend https://my-domain.com/admin - django https://my-domain.com/api - django I can see two possibilities: Django is aware of frontend. Serve everything via Django, setup / as a STATIC_URL. Django is not aware of frontend. Serve /api and /admin via django. / is handled by a webserver. I feel more comfortable with the second approach, however I do not know how to configure VirtualHost for such a scenario. The firstch approach looks like an ugly hack. How should I proceed with that? -

graphql-django update mutation with optional fields idiom?
When implementing GraphQL update mutations with many (here just a and b) optional InputObjectType fields it generates a lot of boilerplate to check if the InputObjectTypes fields have been passed.
