yep, doing it right now! works nicely :smile:

btw, how do you make code colored in this forum?

130

I just use Markdownā€™s triple tick blocks.

131

Can we have multiple if bindings on an element? Or multiple conditions for if

132

Use an expression ā€œif: condition1 && condition2ā€

As weā€™re already at this topic, I know that we can use:

p($b="if: value1 == value2 && value3 == value4") you can see me!

But how can we do:

p($b="if: value1 < value2 && value3 > value4") you can see me too

I get:

Jade syntax error: Expected tag name after `<`

Is it working for HTML?

I know itā€™s easy to work around with global helpers like isGreaterThan etc, but Iā€™m just curious if itā€™s possible to use natively.

Hello,

I was just wondering how you go about using a schema and doing validates with this package? How would this work with simpleSchema for example?

Cheers :slightly_smiling:

135

For me it works with Simple Schema and even Autoform without any problems. What potential issue could you have in mind?

136

@brajt Do you create a new context everytime (mySchema.newContext();). I know that VM and SimpleSchema work together, but I was struggeling how I can handle error messages easily without writing own helpers. Iā€™ve just switched to Astronomy because itā€™s error object was much simpler and easier to use with ViewModel.

137

That my friend is what we call a ā€œbugā€. Iā€™ll check it out.

@brajt Thatā€™s a problem with Jade. The following works as expected:

<body>
  <div {{b "if: value1 < value2 && value3 > value4"}}>It works</div>
</body>

Template.body.viewmodel({
  value1: 1,
  value2: 2,
  value3: 4,
  value4: 3
});

And you can change a value in the console and the UI updates accordingly:
> ViewModel.findOne("body").value4(5)

Thanks. :slight_smile: Iā€™ll have to stay with global helpers then, but at least now I know one more use case when I can recommend Viewmodel when people ask ā€œcan I do that in Blaze?ā€

Hi @manuel,

Thank you for this awesome tool! Though, I havenā€™t used it yet but I think a lot of pain points in blaze are covered by VM.

I would like to ask if this is compatible to autoform?

@brajt looks like youā€™re the unofficial ambassador of VM :slight_smile: Do you have experience integrating autoform and VM?

Thanks!

A bug with the Jade compiler, I think. I may look into it if I find the time. Refer to issue #7.

@dalgard thanks a lot! :slightly_smiling:

@ajaxsoap I use Autoform with Viewmodel for the app Iā€™m currently writing, because Autoform gives me cool Semantic UI form templates integration and more complex form templates by default. But with Viewmodel I donā€™t see the advantage of Autoform being as big as before, as putting forms together with Viewmodel is very easy.

What I didnā€™t manage to do yet is using Viewmodel properties in Autoform hooks. It would be great to learn how to do it, if anybody made it work.

Cool! :+1:

I guess, thatā€™s the reason Iā€™m asking, VM + autoform vs VM + normal form. I havenā€™t had the time to dig deep on VM due to my current dev load but VM is in my roadmap :slightly_smiling:

Thanks!

144

I donā€™t know if itā€™s a bug in VM, jade or spacebars but if: !condition1 && condition2 evaluates to true (element is displayed) if condition1 === false whereas it should always evaluate to false.
Same goes for ||.
if: !condition1 || condition1 doesnt display element when condition1 === true whereas it should.

145

Just read this announcement! Will this effect the availability of the online guide?

146

Iā€™ll move the documentation to another place soon.

147

MDG folks showed an interest in moving it to free Galaxy account, you wonā€™t be interested?

148

Of course, but I only have 2 weeks to do something so I have to operate under the assumption that I have to use my own servers.

For now Iā€™ll just use the money from the videos to pay for the hosting.
