Describe the bug
test.py fails as no 'sample.xer'

To Reproduce
Steps to reproduce the behavior:

1. Go to root
2. Click on launch test.py
3. See error

Traceback (most recent call last):
  File "PyP6Xer/test.py", line 10, in <module>
    r = Reader('sample.xer')
  File "PyP6Xer/xerparser/reader.py", line 282, in __init__
    file = open(filename, 'r')
FileNotFoundError: [Errno 2] No such file or directory: 'sample.xer'

Expected behavior
Getting a short view of the tested file

Congrats @HassanEmam for the impressive and amazing project!
Would it be possible to add some results visualisation to the DCMA-14 point analysis?

• Summary table of the results
• Graphical summary of results

Thanks a lot

When calling the dcma.analysis() method I get the following error

Exception has occurred: AttributeError
'Task' object has no attribute 'get'

Hi @HassanEmam ,
congrats for the amazing project and code, would it be possible to add post-processing visualisation of Earned Value Analysis with:

• PV planned value
• AC actual cost
• EV earned value
• CPI/SPI data

Many thanks!

There are cases when sched_options is not present in the XER and not all add_date are present in the PROJECT data.

for sched_options not present the system stops with this error:
KeyError from line 121 of file venv/Lib/site-packages/xerparser/src/xer.py
maybe if u can check if the sched_options is not present to have a default.

for the add_date are present the system stop with this error:
time data '' does not match format '%Y-%m-%d %H:%M' from line 39 of file venv/Lib/site-packages/xerparser/schemas/project.py
maybe if u can check if it is not present not to assign it or use a default date

Thanks

POBS is usually disregarded as it contains hex characters.

Hi @HassanEmam
There are some XER files where lag value is a decimal like 0.08 or -0.8
The import is raising a conversion error

Hi, first of all congrats for this awesome project! I just started testing it and I am encountering the following error. Could you please help me figure it out?

PS C:\Users\neres\VisualStudio Projects\PyP6Xer trial>

The resources are not being loaded.
I tried both Reader and to reach it from within activity. resources but the it contained only resource assignment primitive information.
example is labor or not.
Is it possible to add the resource object to the individual resource assignment at the activity level

To Reproduce
Attempt to read an XER file with "estimation weight" for a task as a none-float value.

Expected behavior
Reader to successfully parse the file.

Error running the test.py

Dear Dr. Emam,
I am writing this message to contribute an idea that may you find interested to be updated with PyP6Xer. One of the biggest issues we can find is that the changing of the relationship between the activities, more specifically, the changing of the sequence of works. In essence, if I have a project of 8 Buildings or a project divided into many areas, and we need to change the sequence of works between the buildings or the areas, this issue will need loads of efforts to change thousands of relationships between the activities using export and import function with Excel spreadsheet or modifying the relationship on the XER file itself.
My idea is if there is a solution to change the relations using python, then import it into the XER file.

Thanks,
Kareem.

Hi @HassanEmam, I've noticed through exploring a set of XER files that the lag_hr_cnt field within the TASKPRED table may contain float values. This results in a ValueError when attempting to use the Reader since line 31 of taskpred.py is int(params.get('lag_hr_cnt').strip()). Would it be possible to update this line to float instead of int?

I noticed that the end_date is showing the same value as start_date.
I had to use the early_end_date for the meantime.

@hassan this error happened when importing .xer with 11 projects. Could you help? I need to analyze several projects. Thank you!

Describe the bug
Thank you for a great project @HassanEmam!

I would like to use the library to pull out all predecessors to an activity. Once I find the activity and try to print predecessors (project.activity.predecessors) I am getting an error: TypeError("Predecessors.get_predecessors() missing 1 required positional argument: 'act_id'")

Full error:
'Traceback (most recent call last):\n File "location\.vscode\extensions\ms-python.python-2022.20.1\pythonFiles\lib\python\debugpy\_vendored\pydevd\_pydevd_bundle\pydevd_resolver.py", line 192, in _get_py_dictionary\n attr = getattr(var, name)\n File "location\Python\Python310\lib\site-packages\xerparser\model\classes\task.py", line 318, in predecessors\n return Predecessors.get_predecessors(self.task_id)\nTypeError: Predecessors.get_predecessors() missing 1 required positional argument: 'act_id'\n'

Same issue with successors. I am assuming this has something to do with XER file that I have but just wanted to confirm. Thank you!

To Reproduce
Attempt to print predecessors to an activity

My code is straight-forward:

from xerparser.reader import Reader

filename = "my.xer"
xer = Reader(filename) # this returns a reader object

for project in xer.projects:
if(project.proj_short_name == "my_project"):
print("PROJECT: " + project.proj_short_name + "*****")
for activity in project.activities:
if(activity.task_name == "my_activity"):
print("Activity ID | ", activity.task_code, " | Activity Name | ", activity.task_name, " | Pred |", activity.predecessors)
else:
continue

Expected behavior
Print a list of predecessors
