Multiple conditionals with ng-show AngularJS - angularjs

Question

I have a ng-repeat that builds a table from a web service. I render 6 values like this: med:1 lab:1 pl:1 in one cell. I need to make a decision based on those 6 values. My ng-repeat code is like this:
<tr ng-repeat="(pid, value) in patient|groupBy:'pid'">
<td>{{pid}}</td>
<td ng-repeat="(disease, value) in patient|groupBy:'name'">
<span ng-repeat="item in value|filterBy:['pid']:pid" ng-model="disease-conditial">
{{item.src}}:{{item.total}}
</span>
<!--This is the code that I'm trying to make to work-->
<span class="label label-danger" ng-show="
(item.src == 'med' and item.total > 0) and
(item.src == 'lab' and item.total > 0 and
(item.src == 'pl' and item.total > 0))">Yes
</span>
</td>
</tr>
Please consider this sudo code. I need three conditions:
if src == med && total > 0
and
if src == lab && total > 0
and
if src == pl && total > 0
then Yes
if src == med && total == 0
if src == lab && total > 0
if src == pl && total > 0
then Maybe
if src == med && total == 0
if src == lab && total == 0
if src == pl && total == 0
then No
I was reading about ng-switch but this directive doesn't support conditionals with dynamic data $scope.something == 1
Does Angular has any built in directive where I can achieve this?
The data in the cell looks like this:
+-----------------+
|med:1 lab:1 pl:1 |
+-----------------+
I need to evaluate the value of med && the value of lab && the value of pl to make the decision of Yes, Maybe, No.

The data that comes from the object is as follow:
Array[50]
0:Object
$$hashKey:"object:18"
name:"Alcoholism"
pid:"1"
src:"lab"
total:"1"
__proto__:Object
1:Object
$$hashKey:"object:19"
name:"Alcoholism"
pid:"1"
src:"med"
total:"1"
__proto__:Object
2:Object
$$hashKey:"object:20"
name:"Alcoholism"
pid:"1"
src:"pl"
total:"0"
__proto__:Object
Once again, scenario 1. if med > 0 && lab >0 && pl >0 then Yes. Scenario 2. if med == 0 && lab > 0 && pl > 0 then Maybe. Scenario 3. if med == 0 && lab == 0 && pl == 0 then No.

Answer 1

You can use a ng-switch with item.src like this:
<div class="animate-switch-container" ng-switch on="item.src" ng-show="item.total > 0">
<div ng-switch-when="med">med</div>
<div ng-switch-when="lab">lab</div>
<div ng-switch-when="pl">pl</div>
</div>
With the ng-show in the entire div will make the same and validation.

Answer 2

I ill prefer you to get single value from controller which you want to display on view but ng-bind can also help you render required data
<span class="label label-danger" ng-bind="item.total>0 && (item.src === 'med' || item.src === 'lab' || item.src === 'pl')?'yes':'no'"> </span>

Answer 3

I think you are just putting your conditions wrong. I'm doing some guessing here, but what I think you are trying to do is this:
<tr ng-repeat="(pid, value) in patient|groupBy:'pid'">
<td>{{pid}}</td>
<td ng-repeat="(disease, value) in patient|groupBy:'name'">
<span ng-repeat="item in value|filterBy:['pid']:pid" ng-model="disease-conditial">
{{item.src}}:{{item.total}}
</span>
<!--This is the code that I'm trying to make to work-->
<span class="label label-danger" ng-show="
((item.src == 'med' || item.src == 'lab' || item.src == 'pl') and item.total > 0)">
Yes
</span>
<span class="label label-danger" ng-show="
((item.src == 'med' && item.total == 0) || (item.src == 'lab' and item.total > 0) || (item.src == 'pl' and item.total > 0))">
Maybe
</span>
<span class="label label-danger" ng-show="
((item.src == 'med' || item.src == 'lab' || item.src == 'pl') and item.total == 0)">
No
</span>
</td>
</tr>
It is not a problem with the ng-show directive, it is a problem with the conditions inside it.
