[tw5] Re: Show table of checkboxes with labels based off a DataTiddler

2020-03-23 Thread 'Mark S.' via TiddlyWiki 
I've just updated the grocery list showing how this might be done.

The problem with not showing empty sections is then, how do you get them 
back? So I've put in a select list that lets you choose whether to show 
empty sections or not.

Probably I will also add a select option whether to show individual items, 
checked items, unchecked items, or recurring items. I will probably put the 
"sections" and "Retailer" in their own tiddlers. After this, the 
"recurring" section will no longer be needed, because you'll be able to 
select within the "Sections" list.

There will probably also be an ability to turn off the "real" checkboxes 
and swap in text-based boxes (e.g.[_] Razor Wire) so that the text can be 
copied and pasted into a word processor. This process is what I do in my 
actual grocery list app (which is outdated).

Hello Mark S.
Thanks very much for posting your example online.
I would like to modify it, but I'm not sure how to do it, to achieve what I 
would like.

Is it possible to show a list of Items by Section, but only show the 
section and item, where the items have been selcted.
My example below, shows Sections with no Items which are not required.

Any help you could offer would be much appreciated.

Yes, I've definitely run into that kind of problem before. 

But in the case of a TODO list, I would rather have a data entry error show 
up under another category, instead of not showing up at all.  If I put in a 
TODO Task and did it quickly without checking to make sure it showed up, I 
could then disappear if I didn't categorize it correctly.

I would then later spot it under the wrong category and then correct it.

Or I guess if we kept to the static list, we could add some kind of 
exclusion to pick up the strays and put them at the bottom of the list 
under a section with a title like "Miscategorized" or something like that.

You could do this with a nested <$list> structure.

The reason, or one of the reasons, I didn't do it this way to avoid the 
problem that happens when you let people set up "sections" (or any data 
attribute) on the fly. You tend to end up with either too many "sections", 
or "sections" with different values (spellings, misspellings, plurals, 
etc.) but for the same thing. e.g.

Garden
Gardeen
Gardening
Gardens
gardens
OutdoorGarden
Yardwork

Having one central location for the sections helps you to think clearly 
about what values you want "sections" to contain. Then the drop-down list 
allows you to easily select and apply that section to new items. If you 
really want more sections then it's easy enough to add them to the driver 
tiddler. Believe me, if you've ever inherited a database where someone has 
freely entered anything they happened to be thinking of at 9am on a Monday 
morning, then you'll know what I'm talking about.

[tw5] Re: Show table of checkboxes with labels based off a DataTiddler

2020-03-22 Thread David 
This is great, but if I may offer one change so that your example could be 
more easily graspable by noobs like me  you used the string "section" 
to represent two different things.  It's a field in the data tiddlers as 
well as your item iterator variable in the section loop.

when I started to switch over your code to my data paradigm, It took me 
several hours of working with your code and googling (there's not a lot of 
noob-friendly info out there that's easy to find) to discover that.  

The good news is I learned a lot.  And I've also had a lot of fun putting 
together my own Grocery lister, and I was easily able to start a new set of 
Data Tiddlers and another lister for my TODO tasks as well, sectioning them 
by the context in which the task should be done (e.g. home, office hours, 
or out and about).

I saw how you set "sections" up as a tiddler, containing the names of the 
sections.  It would be great if there were a dynamic way to get a list of 
the sections.  For my grocery list, they are all tagged with 
"ShoppingItem".  Is there a way to create that list by searching all the 
tiddlers tagged "ShoppingItem" and grab the different values in their 
"section" field dynamically?

This has been so helpful!
Thank you!

[tw5] Re: Show table of checkboxes with labels based off a DataTiddler

2020-03-19 Thread 'Mark S.' via TiddlyWiki 

I've used a slightly different structure, to leverage the tag and list 
fields.

Grocery tiddlers are tagged with "Item", and have the following special 
fields:

tags: (one or more of) Item Selected
sections: (field indicating the section where the item can be found)
retailers: (list field with retailers)

An item tagged with "Item" is a grocery/shopping item. An item also tagged 
with "Selected" is selected for the current shopping list / week. Items 
tagged "Recurring" will appear on the recurring list.

There is a special tiddler Retailers that has a list of all retailers in 
its list field.
There is a special tiddler Sections that has a list of all sections in its 
list field.

A view template helps you select or remove retailers.

There is a lister tiddler that lists your items, as you asked. Here is a 
screenshot:


The attached contains the starter kit. Back up any work you have started. 
Or better yet, use a fresh empty TW file. Download the attached. Drag and 
drop into your TW file (a green bar should appear at the top). Import the 
tiddlers. There are many improvements that could be made. For instance, 
making each item in the grocery list a link might be useful.

It's left as an exercise to add "sections" to the grocery view template.

I should probably post this in it's own TW page somewhere.

[tw5] Re: Show table of checkboxes with labels based off a DataTiddler

2020-03-19 Thread David 
Mark,

So would each tiddler become like a row in a database table?

And would the columns of that row be colon separated values like a data 
tiddler?  Example:

Tiddler Name: $:/data/ShoppingItems/Milk

Tiddler content:

buyItThisWeek: yes
recurringWeeklyItem: yes
storeSection: Dairy
atSamsClub: yes
atLidl: yes

And then could you throw together some code to give me a list of all the 
"data" tiddlers with a prefix of "$:/data/ShoppingItems/" that have a 
"buyItThisWeek" value of "yes"?  

And bonus points for having the list sorted by store section. 

I think that would lay down a nice groundwork for me to build on and use as 
a pattern as I study the listWidget.

Thanks so much if you can!

2020-03-16 Thread TonyM 
David,

Herre is a little code from and existing solution I built

The fieldnames are extracted from the data tiddler and a list of only those 
"checked" is displayed in read only view, in edit view a checkbox is 
presented for all fieldnames.

This is read only/view
<$list filter="[[$:/data/industry-experience-fields]indexes[]]" 
variable=fieldname>
<$list filter="[all[current]getmatch[yes]]" variable=nul>
   <$text text={{{ [[$:/data/industry-experience-fields]getindex
] }}}/>




This is edit or checkbox mode
<$list filter="[[$:/data/industry-experience-fields]indexes[]]" 
variable=fieldname>
  <$checkbox field=<>  checked="yes" unchecked="no" 
default="no"> <$text text={{{ [[$:/data/industry-experience-fields]getindex
] }}}/>


Regards
Tony

David, you must learn to use the listwidget. It is probably the *most* 
central widget of them all for creating stuff. I'd say 80-90% of everything 
I make in TW centers around the listwidget. If you're a programmer... 
you'll get it quickly once you actually play around with it. In fact, what 
I think you mean is difficult is really the filter attribute. Yes, filters 
can take some getting used to... but they are central for the listwidget 
so, them too, you must ;-)

I would love to learn more about the ListWidget.  I looked at that main 
page and it was just too complicated for me at this point.  I'm a 
programmer, but a TW noob.

[tw5] Re: Show table of checkboxes with labels based off a DataTiddler

2020-03-16 Thread 'Mark S.' via TiddlyWiki 
I think newcomers sometimes gravitate towards the data tiddler, because it 
seems familiar. But really, the main data element in TW isn't the data 
tiddler, which are pretty limited, but the tiddler themselves. The problem 
with using a data tiddler is that it will record a single bit of 
information for each item. Like "buy/don't buy". But what if you have one 
item that you can get from two different places? Or if you want to indicate 
what kind of product it its (produce, hardware, canned, cleaning, etc.) ? 

The best thing to learn is the list widget, and the filters it uses. 

I use a TW grocery list every week. I suppose I should sanitize it and post 
a version. I haven't kept it up to 5.1.20 capabilities ... but sometimes 
"good enough" is the enemy of "perfect."

Ok, back to your question.

Let's say you have a data tiddler like:

ShoppingSamsClubData 

with

 
Aardvarks: yes 

Kittens: no
Puppies: yes

Then in a tiddler you can put:

<$tiddler tiddler="ShoppingSamsClubData">
<$list filter="[all[current]indexes[]sort[]]" variable=item>
<$checkbox index=<> checked="yes" unchecked="no"/> <>




And it will give you a dynamic list like (you should see a screen shot here):


I guess if all you ever want is to shop at Sam's club, then you're good to 
go!
